pure sine wave inverter test has to answer two different questions, and most guides only answer the first: is this inverter genuinely producing a sine wave, and does it <\/span><i><span

At Impedyme, we validate power electronics for a living, and we see the same pattern constantly \u2014 an inverter that looks flawless at no load collapses into visible distortion the moment a switch-mode power supply or a motor is connected. This guide walks through the complete pure sine wave inverter test workflow, from a two-minute quick check you can do with basic instruments, to a defensible bench characterization with real pass\/fail criteria, to closed-loop hardware-in-the-loop validation for teams who need repeatable, standards-referenced proof.

A true sine wave inverter test rests on four measurable pillars: voltage total harmonic distortion, waveform-shape ratios (crest factor and form factor), frequency and voltage regulation, and DC offset. None of these numbers means anything on its own \u2014 each is only meaningful with a stated load, load type, and DC input condition attached.<\/span><\/p><h3><span style=\"color: #d18100;\">Voltage THD, and why the load condition matters more than the number<\/span><\/h3><p><span style=\"font-weight: 400;\">Total harmonic distortion of the output voltage is the single number that correlates most strongly with &#8220;grid-like&#8221; power. It expresses how much harmonic content rides on top of the fundamental 50 or 60 Hz sine. Quality pure sine wave inverters are commonly specified with voltage THD below 3 percent, and the best hold well under that.<\/span><\/p><p><span style=\"font-weight: 400;\">Here is the problem with almost every published pure sine wave inverter THD test: the number is quoted with no conditions. THD at no load is nearly meaningless, because with nothing drawing current the output filter has an easy job and almost any half-decent inverter looks clean. The distortion appears under load \u2014 specifically under non-linear load, where the current is drawn in narrow high peaks that the inverter&#8217;s output stage struggles to supply without the voltage waveform sagging at its crest. A THD figure without a stated load percentage, load type, and DC input voltage is not a specification; it is a decoration. Every THD number produced by a credible inverter waveform test must carry those three conditions.<\/span><\/p><h3><span style=\"color: #d18100;\">Crest factor and form factor as waveform-shape indicators<\/span><\/h3><p><span style=\"font-weight: 400;\">Crest factor is the ratio of a waveform&#8217;s peak value to its RMS value. For a mathematically perfect sine wave, crest factor is always 1.414 \u2014 the square root of two \u2014 regardless of amplitude. If you measure the output voltage crest factor of an inverter and it reads meaningfully below 1.414, the waveform is flat-topped (clipped at the peak); if it reads well above, the wave is peaky. Either way, the departure from 1.414 is a fast, load-dependent indicator of distortion.<\/span><\/p><p><span style=\"font-weight: 400;\">Form factor, the ratio of RMS value to the average of the rectified waveform, is 1.11 for a pure sine. Form factor is the quiet hero of low-cost sine wave inverter output testing, because it is exactly the constant that cheap meters bake into their circuitry \u2014 and, as we explain below, that is what lets a two-meter comparison expose distortion.<\/span><\/p><h3><span style=\"color: #d18100;\">Frequency and voltage regulation limits<\/span><\/h3><p><span style=\"font-weight: 400;\">A pure sine wave inverter should hold its output frequency and RMS voltage tightly as the load and DC input change. Good standalone inverters regulate steady-state output voltage to within a couple of percent, and premium double-conversion designs specify steady-state voltage regulation as tight as plus or minus 1 percent. Frequency on a crystal-referenced inverter is typically held within a fraction of a percent. The test that matters is not whether these hold at a single operating point, but whether they hold across the <\/span><i><span style=\"font-weight: 400;\">full<\/span><\/i><span style=\"font-weight: 400;\"> DC input range and the <\/span><i><span style=\"font-weight: 400;\">full<\/span><\/i><span style=\"font-weight: 400;\"> load range simultaneously.<\/span><\/p><h3><span style=\"color: #d18100;\">Typical pure sine wave inverter test thresholds<\/span><\/h3><p><span style=\"font-weight: 400;\">The table below gives defensible target thresholds with their measurement conditions attached.

A rigorous pure sine wave inverter test procedure is a sequence of ten steps, each with a defined purpose, setup, what to record, and a pass\/fail criterion. Run them in order \u2014 each builds on the last, and skipping the early ones puts your instruments and your people at risk.<\/span><\/p><h3><span style=\"color: #d18100;\">Step 1 \u2014 Visual, wiring, and insulation checks<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Confirm the unit is safe to energize and that nothing will introduce false readings or hazards. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> With everything de-energized, inspect terminals, torque connections to spec, verify conductor sizing, and check the chassis ground bond. Perform an insulation resistance check between input, output, and chassis. <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> Insulation resistance values, torque confirmation, any physical damage. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> Insulation resistance meets the manufacturer&#8217;s and the applicable safety standard&#8217;s minimum; no loose connections; a solid protective earth. Fail here and you stop \u2014 there is no point measuring waveforms on an unsafe unit.<\/span><\/p><h3><span style=\"color: #d18100;\">Step 2 \u2014 DC input verification and input range sweep<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Prove the inverter behaves across its entire DC input window, not at one convenient voltage. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> Feed the inverter from an adjustable DC source (a programmable supply or a battery emulator) rather than a single fixed battery. Sweep the DC input from the low-voltage cutoff, through nominal, to the high-voltage limit. <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> Output voltage, frequency, and THD at each DC input point at a fixed moderate load. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> Output stays within regulation limits and THD stays within target across the whole DC range. This step routinely exposes inverters that are clean at nominal battery voltage but distort badly near the low-battery cutoff, when the DC bus ripple grows and the output stage runs out of headroom.<\/span><\/p><h3><span style=\"color: #d18100;\">Step 3 \u2014 No-load output voltage, frequency, and waveform baseline<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Establish a clean reference before loading. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> Inverter energized, no load, differential probe on the output (see safety section). <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> RMS voltage, frequency, waveform capture, no-load THD, crest factor, and \u2014 importantly \u2014 standby\/no-load DC draw. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> Voltage and frequency at nominal; waveform visually sinusoidal.

A non-linear load \u2014 every switch-mode power supply, LED driver, laptop charger, and TV \u2014 draws current only near the voltage peak, in tall narrow pulses. Supplying that pulse without the voltage sagging demands a stiff output stage and a fast control loop. Undersized inverters cannot deliver the peak current, so the top of the sine gets clipped, THD shoots up, and connected electronics see distorted power. We have watched inverters that advertise clean sine output distort violently the instant a modest computer power supply is connected. If you run only one step of this pure sine wave inverter test, run this one.<\/span><\/p><h3><span style=\"color: #d18100;\">Step 6 \u2014 Step-load and transient response<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Measure dynamic regulation \u2014 how the inverter reacts to sudden load changes. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> Switch the load abruptly between defined points (for example 0 to 100 percent, and 20 to 100 to 20 percent) for both resistive and non-linear loads while capturing the output on a scope. <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> Peak voltage dip and overshoot, and the recovery time back to within tolerance. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> As a reference, IEC 62040-3 Class 1 requires the output voltage to recover within 200 milliseconds after a 0-to-100 percent or 100-to-0 percent step load change, with the transient voltage deviation held within plus or minus 10 percent of nominal. Excessive dips cause connected equipment to reset or drop out even though the inverter never &#8220;failed.&#8221;<\/span><\/p><h3><span style=\"color: #d18100;\">Step 7 \u2014 Overload, inrush, and short-circuit protection<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Confirm the inverter survives and protects itself against abnormal loads. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> Apply defined overloads above 100 percent, a high-inrush load (such as a motor or a load with a large input capacitor), and a controlled output short. <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> Overload duration before trip, behavior during motor-start inrush, short-circuit trip time, and whether the unit recovers or latches off. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> The inverter rides through rated surges, trips cleanly on genuine overload and short circuit within its declared times, and either restarts or latches per its specification \u2014 without damage.

This pure sine wave inverter efficiency test is where paper specifications most often fail to survive contact with a meter.<\/span><\/p><h3><span style=\"color: #d18100;\">Step 10 \u2014 Protection functions and shutdown thresholds<\/span><\/h3><p><b>Purpose:<\/b><span style=\"font-weight: 400;\"> Verify every declared protection actually fires at the right threshold. <\/span><b>Setup:<\/b><span style=\"font-weight: 400;\"> Individually exercise low-battery warning and shutdown, high-battery\/over-voltage shutdown, over-temperature shutdown, and any ground-fault or reverse-polarity protection. <\/span><b>Record:<\/b><span style=\"font-weight: 400;\"> The measured threshold and response for each function against its specified value. <\/span><b>Pass\/fail:<\/b><span style=\"font-weight: 400;\"> Each protection activates within its declared window and the unit annunciates the condition.

These methods can build or destroy confidence quickly, but each has hard limits \u2014 and knowing what a method <\/span><i><span style=\"font-weight: 400;\">cannot<\/span><\/i><span style=\"font-weight: 400;\"> prove is as important as knowing what it can.<\/span><\/p><h3><span style=\"color: #d18100;\">Oscilloscope on the output \u2014 the only direct inverter waveform test<\/span><\/h3><p><span style=\"font-weight: 400;\">An oscilloscope is the only way to <\/span><i><span style=\"font-weight: 400;\">see<\/span><\/i><span style=\"font-weight: 400;\"> the waveform directly, and a genuine pure sine looks like a smooth sinusoid while a modified sine shows an obvious stepped, blocky shape. But connecting a scope to a live AC inverter output is where people destroy equipment and hurt themselves. Read the safety section below before you do this. Done correctly with a differential probe, the scope tells you shape at a glance; with the scope&#8217;s math functions you can also read THD and crest factor.<\/span><\/p><h3><span style=\"color: #d18100;\">The true-RMS versus average-responding meter comparison, done correctly<\/span><\/h3><p><span style=\"font-weight: 400;\">There is a widespread and flatly incorrect claim that a true-RMS meter &#8220;reveals&#8221; a bad waveform by reading erratically or low. That is wrong, and it is worth being precise because getting this right is a genuine authority signal. A true-RMS meter reads the <\/span><i><span style=\"font-weight: 400;\">correct<\/span><\/i><span style=\"font-weight: 400;\"> RMS value regardless of waveform shape \u2014 that is the entire point of it. It will not flag distortion by misbehaving, because it does not misbehave.<\/span><\/p><p><span style=\"font-weight: 400;\">The correct low-cost technique is a <\/span><i><span style=\"font-weight: 400;\">comparison<\/span><\/i><span style=\"font-weight: 400;\">. Measure the same inverter output with two meters at once: a true-RMS meter and an ordinary average-responding meter (the cheaper kind, internally calibrated to display RMS by assuming a sine and applying the 1.11 form-factor constant). On a genuine pure sine wave, both meters agree closely. On a distorted or modified-sine output, the average-responding meter&#8217;s built-in sine assumption breaks down and its reading diverges from the true-RMS meter \u2014 published instrument guidance puts that error as much as 40 percent low or 10 percent high depending on the waveform. A meaningful gap between the two readings is your evidence of distortion, and the size and direction of the divergence hints at the waveform type. This version of a true sine wave inverter test costs two handheld meters and proves far more than either meter alone.<\/span><\/p><h3><span style=\"color: #d18100;\">Incandescent bulb and transformer-hum checks, and their limits<\/span><\/h3><p><span style=\"font-weight: 400;\">An old-fashioned incandescent bulb runs smoothly on a sine and can flicker or buzz on a distorted wave; a small mains transformer or a cheap AC motor often emits a louder, harsher hum on a distorted output than on a clean one. These sensory checks are quick and free. Their limit is that they are qualitative \u2014 they can suggest gross distortion but cannot confirm a 3-percent-THD claim, cannot attach a number to anything, and can be fooled. Use them to raise suspicion, never to certify.<\/span><\/p><h3><span style=\"color: #d18100;\">Reading the nameplate and datasheet critically<\/span><\/h3><p><span style=\"font-weight: 400;\">The most underrated part of any pure sine wave inverter test is reading the datasheet properly. A THD spec almost always omits the conditions that make it meaningful: at what load, what load type, and what DC input? &#8220;THD under 3%&#8221; with no load stated is very likely a no-load figure \u2014 the flattering one. Look for THD quoted at rated load and, ideally, at a reference non-linear load; look for voltage and frequency regulation stated across the DC input range; look for a declared standby draw and an efficiency curve rather than a single peak number. What a spec <\/span><i><span style=\"font-weight: 400;\">omits<\/span><\/i><span style=\"font-weight: 400;\"> tells you as much as what it states.<\/span><\/p><h2><span style=\"color: #000000;\">Pure sine wave inverter test bench setup and measurement safety<\/span><\/h2><h3><span style=\"color: #d18100;\">Instruments required<\/span><\/h3><p><span style=\"font-weight: 400;\">A defensible bench needs, in generic terms: a digital oscilloscope with adequate bandwidth; a high-voltage differential probe rated for the output; a power analyzer or power quality analyzer for THD, power, and efficiency; a true-RMS meter and an average-responding meter for the comparison check; a programmable DC source or battery emulator for the input sweep; and a programmable AC load or load bank capable of both resistive and non-linear (crest-factor) profiles. We deliberately name no brands \u2014 categories are what matter.<\/span><\/p><h3><span style=\"color: #d18100;\">Differential probes, isolation, and floating outputs \u2014 the mistake that damages equipment<\/span><\/h3><p><span style=\"font-weight: 400;\">This is the single most important safety point in the whole procedure. A standard oscilloscope&#8217;s probe ground clip is connected, through the scope&#8217;s power cord, to earth ground. An inverter output is frequently floating or line-referenced, not earth-referenced. Clip a normal probe ground onto an inverter&#8217;s live or neutral and you can create a direct short through the scope chassis to earth \u2014 destroying the probe, the scope, and potentially injuring the operator. Never do it.<\/span><\/p><p><span style=\"font-weight: 400;\">The correct method is a high-voltage differential probe, which measures the voltage <\/span><i><span style=\"font-weight: 400;\">between<\/span><\/i><span style=\"font-weight: 400;\"> two points without referencing either to earth and rejects the common-mode voltage safely. An isolated-input oscilloscope achieves the same end. &#8220;Floating&#8221; the scope by defeating its earth ground is dangerous and must not be done. Any instruction to clip a scope directly across a live inverter output with no mention of isolation \u2014 as some published guides unfortunately give \u2014 is simply wrong and unsafe.<\/span><\/p><h3><span style=\"color: #d18100;\">Bandwidth, sample rate, and window length for meaningful harmonic measurement<\/span><\/h3><p><span style=\"font-weight: 400;\">To run an inverter THD test honestly you must capture the harmonics, not just the fundamental. Harmonic content of interest typically extends to the 40th or 50th harmonic, so your instrument&#8217;s bandwidth and sample rate must comfortably cover that range \u2014 a measurement chain that rolls off too early will report a flatteringly low THD. Capture over several full cycles so the analysis window contains enough periods for a stable harmonic spectrum, and let readings settle before logging. Measurement conditions \u2014 bandwidth, window, load \u2014 belong in the test record alongside the numbers.<\/span><\/p><h3><span style=\"color: #d18100;\">DC source and load selection<\/span><\/h3><p><span style=\"font-weight: 400;\">Use a DC source that can be swept across the inverter&#8217;s full input range and that can reproduce battery-like behavior, not just a stiff bench supply.

The 2021 edition changed this: the non-linear step load is no longer a type test, and non-linear load requirements were relaxed in the annex for consistency with the IEC 61000-3 harmonic standards. If you cite a specific crest factor or power split in a test report, cite it against the edition you are working to.<\/span><\/p><h2><span style=\"color: #000000;\">Where bench-based pure sine wave inverter testing stops being enough<\/span><\/h2><p><span style=\"font-weight: 400;\">Everything above is real, valuable work \u2014 and it has genuine technical limits that no amount of care on a physical bench can remove.<\/span><\/p><p><span style=\"font-weight: 400;\">Some conditions are unsafe or impossible to create repeatably with real hardware. Deliberately driving an inverter into repeated short circuits, or forcing an internal switch fault, stresses and eventually destroys real devices, and each destructive event happens slightly differently, so results scatter. Sweeping the DC input across the <\/span><i><span style=\"font-weight: 400;\">full<\/span><\/i><span style=\"font-weight: 400;\"> battery state-of-charge and temperature range with real batteries means waiting for real charge\/discharge cycles and real thermal soaks \u2014 days per point, and impossible to hold perfectly steady. Grid disturbances \u2014 voltage sags, frequency excursions, phase jumps \u2014 cannot be conjured on demand at a wall outlet, and creating them with real fault hardware is hazardous. And every time firmware changes, you would ideally re-run the entire pure sine wave inverter test campaign for regression; doing that on a physical bench is slow, expensive, and throughput-limited. Physical benches are also destructive-risk-limited: you cannot afford to blow up ten units to characterize a protection threshold ten times. These are not reasons to abandon the bench; they are the precise boundary where hardware-in-the-loop takes over.<\/span><\/p><h2><span style=\"color: #000000;\">Controller HIL testing for pure sine wave inverters<\/span><\/h2><p><span style=\"font-weight: 400;\">Hardware-in-the-loop testing replaces the physical power environment with a real-time digital simulation while keeping the real controller hardware in the loop. For a pure sine wave inverter, controller HIL means the inverter&#8217;s control board runs against a simulated power stage, output filter, load, and source \u2014 with no real high power involved.<\/span><\/p><h3><span style=\"color: #d18100;\">What gets modeled<\/span><\/h3><p><span style=\"font-weight: 400;\">The real-time model represents the switching power stage, the LC output filter that turns the PWM chopping into a smooth sine, the load (linear or non-linear, with whatever crest factor you choose), and the DC source. The controller thinks it is driving real hardware; in fact it is driving a faithful digital twin that you can reconfigure in seconds.<\/span><\/p><h3><span style=\"color: #d18100;\">Why time step and FPGA resolution decide whether your results are trustworthy<\/span><\/h3><p><span style=\"font-weight: 400;\">This is where the physics gets unforgiving. A pure sine wave inverter&#8217;s waveform quality is created by PWM switching at several kilohertz to tens of kilohertz, smoothed by the output filter. If your simulation time step is too coarse, the model cannot place the PWM edges accurately, and every harmonic conclusion drawn from it is suspect. Published analysis of real-time simulation loops shows that a 25-microsecond time step can carry as much as 20 percent relative error against an 8 kHz PWM, while the same simulation at 1 microsecond drops to well under 1 percent. The peer-reviewed literature draws the same line: accurate power electronic simulation with a PWM control strategy should run under 1 microsecond \u2014 territory that requires FPGA-based execution rather than a CPU. On Impedyme&#8217;s FPGA-based platform, model updates run as fast as 90 nanoseconds and PWM gate edges are captured at nanosecond-scale resolution, which is what makes the emulated waveform&#8217;s harmonic content trustworthy enough to test against a THD limit.<\/span><\/p><h3><span style=\"color: #d18100;\">Testing control firmware directly<\/span><\/h3><p><span style=\"font-weight: 400;\">Controller HIL lets you exercise the firmware itself \u2014 the PWM generation, the closed-loop voltage and frequency regulation, and the protection logic \u2014 under conditions you fully control. You can watch how the control loop responds to a modeled non-linear load, whether it maintains regulation as the modeled DC bus sags, and whether its protection state machine trips correctly, all without risking a single real component.<\/span><\/p><h3><span style=\"color: #d18100;\">Automated fault injection and regression suites<\/span><\/h3><p><span style=\"font-weight: 400;\">Because the environment is simulated, faults are just parameters. You can inject a short, an open switch, a sensor fault, or a grid disturbance on a schedule, repeat it identically a thousand times, and re-run the entire pure sine wave inverter test campaign automatically after every firmware change. This turns regression testing from a multi-week hardware exercise into an overnight automated run \u2014 the single biggest reason validation teams adopt HIL.<\/span><\/p><h2><span style=\"color: #000000;\">Power HIL (PHIL): pure sine wave inverter testing against an emulated world<\/span><\/h2><p><span style=\"font-weight: 400;\">Power hardware-in-the-loop goes a decisive step further: the <\/span><i><span style=\"font-weight: 400;\">real, fully powered<\/span><\/i><span style=\"font-weight: 400;\"> inverter runs against an emulated electrical environment, exchanging actual voltages and currents with programmable power hardware driven by the real-time model.

How do you test if an inverter is a true pure sine wave?<\/strong> Put an oscilloscope with a differential probe on the output to see the shape directly, and measure voltage THD under load with a power analyzer. As a low-cost cross-check, compare a true-RMS meter reading against an average-responding meter on the same output \u2014 a genuine sine makes them agree, while distortion makes them diverge. Always test under load, not just no load.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>2. What THD is acceptable for a pure sine wave inverter?<\/strong> Quality units are commonly specified below 3 percent voltage THD, but the number is meaningless without conditions. Expect under about 2 percent at no load, under 3 percent at rated resistive load, and under about 5 percent at a reference non-linear load with a crest factor near 3. Always demand the load, load type, and DC input at which any THD figure was measured.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>3. Can you run a pure sine wave inverter test with just a multimeter?<\/strong> Partly. Two multimeters \u2014 one true-RMS, one average-responding \u2014 let you detect distortion by comparing their readings on the same output; a meaningful gap indicates a non-sinusoidal wave. But a multimeter cannot show you the waveform, cannot quantify THD, and cannot capture transient behavior. It is a screening tool, not a substitute for an oscilloscope and power analyzer.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>4. Why does a pure sine wave inverter distort under load?<\/strong> Non-linear loads such as switch-mode power supplies draw current in tall, narrow pulses near the voltage peak. Supplying that peak current without the voltage sagging demands a stiff output stage and a fast control loop. Undersized or cheap inverters cannot, so the sine gets flat-topped at its crest, THD rises, and the distortion appears exactly when a real non-linear load is connected.<\/p><p class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"><strong>5. Is it safe to connect an oscilloscope to an inverter output?<\/strong> Only with a high-voltage differential probe or an isolated-input scope. A normal probe&#8217;s ground clip is tied to earth through the scope; an inverter output is often floating or line-referenced, so a direct connection can create a short through the scope chassis, destroying equipment and endangering the operator. Never &#8220;float&#8221; the scope by defeating its earth ground.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1cbeb78 elementor-align-center elementor-widget__width-inherit elementor-widget elementor-widget-button\" data-id=\"1cbeb78\" data-element_type=\"widget\" data-rp-stop=\"true\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-sm\" href=\"https:\/\/impedyme.com\/contact\/\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t\t\t\t<span class=\"elementor-button-text\">Request a Demo<\/span>\n\t\t\t\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-57472ea e-con-full e-flex e-con e-child\" data-id=\"57472ea\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-885d9ad elementor-widget elementor-widget-text-editor\" data-id=\"885d9ad\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<!-- ============================================================\n     RELATED PRODUCTS \u2014 sticky sidebar (follows scroll, then stops\n     at the \"Request a Demo\" button).
