The Test Bench Challenge: Why Power Supply Quality Determines Measurement Accuracy<\/h2>\n<p>Test benches and measurement systems are the foundation of electronics validation. Whether characterizing a new semiconductor device, calibrating a sensor, or running production acceptance tests, the accuracy and repeatability of the measurements depend on the stability of the power supplied to the device under test (DUT).<\/p>\n<p>A power supply that introduces ripple, noise, or voltage drift directly contaminates the measurement. Consider these common scenarios:<\/p>\n<ul>\n<li><strong>Analog measurements:<\/strong> A power supply with 100mV of ripple on a 3.3V rail introduces a 3% error\u2014enough to mask true device performance and cause false failures<\/li>\n<li><strong>Low-power devices:<\/strong> Measuring the sleep current of a microcontroller in the microamp range requires a power supply with noise floor below the measurement threshold<\/li>\n<li><strong>Dynamic loads:<\/strong> A device that switches between operating modes draws transient currents; a power supply with slow transient response causes voltage droops that can reset the device or corrupt measurements<\/li>\n<li><strong>Sensor characterization:<\/strong> Precision sensors\u2014strain gauges, RTDs, pressure transducers\u2014require stable excitation voltage; power supply noise directly translates to measurement noise<\/li>\n<\/ul>\n<p>For system integrators and electrical engineers, the challenge is selecting an <strong>industrial test power system<\/strong> that meets the specific requirements of each test bench. The power supply must deliver not only the required voltage and current but also the precision, stability, and programmability needed for reliable, repeatable measurements.<\/p>\n<p>TPS Elektronik&#8217;s <strong>industrial power supply systems<\/strong> are designed to meet these demanding requirements, delivering the precision and stability that test and measurement applications demand.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-18023\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/09\/Industrial-Power-Supply-System-for-Test-Bench-and-Measurement-Equipment-1-1.jpg\" alt=\"Industrial Power Supply System for Test Bench and Measurement Equipment Industrielles Stromversorgungssystem f\u00fcr Pr\u00fcfst\u00e4nde und Messger\u00e4te\" width=\"1920\" height=\"1079\" \/><\/p>\n<p><a class=\"cta-primary\" href=\"https:\/\/tps-elektronik.com\/en\/custom-power-supply\/\">Learn more about TPS custom power supplies \u2192<\/a><\/p>\n<\/section>\n<section id=\"precision-regulation\">\n<h2>2. Precision Regulation and Low Ripple: The Foundation of Stable Test Power<\/h2>\n<p>The quality of a power supply for test bench applications is defined by three key parameters: regulation, ripple, and transient response. These parameters determine how well the power supply maintains a stable output voltage under varying conditions.<\/p>\n<p><strong>Regulation:<\/strong> Load regulation measures how much the output voltage changes when the load current changes from no load to full load. Line regulation measures how much the output voltage changes when the input AC voltage varies. For precision test applications, both parameters should be well below 0.1%.<\/p>\n<p><strong>Ripple and Noise:<\/strong> Ripple is the residual AC component superimposed on the DC output. It originates from the switching frequency of the power supply and its harmonics. For sensitive measurements, low ripple is essential\u2014typically measured in millivolts RMS or peak-to-peak. TPS power supplies achieve ripple as low as 10mV RMS and 80mV peak-to-peak, ensuring clean DC power for even the most sensitive measurements.<\/p>\n<p><strong>Transient Response:<\/strong> When a load changes suddenly\u2014for example, when a digital device switches from sleep to active mode\u2014the power supply must respond quickly to maintain voltage stability. TPS power supplies achieve load regulation times of less than 1ms, ensuring that voltage remains stable during rapid load changes.<\/p>\n<p>For <strong>measurement equipment power<\/strong> applications, these specifications translate directly to measurement confidence. A power supply with excellent regulation, low ripple, and fast transient response ensures that measured variations are due to the DUT, not the power source.

Powering Automated Test Equipment (ATE) Systems<\/h2>\n<p>Automated test equipment (ATE) systems are the backbone of high-volume production testing. These systems require power supplies that can be controlled programmatically, deliver multiple output voltages, and integrate seamlessly into test automation software.<\/p>\n<p>Key requirements for <strong>ATE power supply systems<\/strong> include:<\/p>\n<ul>\n<li><strong>Programmability:<\/strong> Voltage and current setpoints must be controllable via SCPI commands, LabVIEW, or other test automation software<\/li>\n<li><strong>Multiple outputs:<\/strong> ATE systems often require multiple independent voltage rails\u2014for example, 3.3V for digital logic, 5V for analog, and 12V for communication interfaces<\/li>\n<li><strong>Fast settling time:<\/strong> When switching between test conditions, the power supply must settle quickly to minimize test time<\/li>\n<li><strong>Remote sensing:<\/strong> For accurate voltage at the DUT, the power supply must compensate for voltage drops in test cables and fixtures<\/li>\n<li><strong>Comprehensive protection:<\/strong> ATE systems test valuable devices; the power supply must protect against overvoltage, overcurrent, and overtemperature conditions<\/li>\n<\/ul>\n<p>TPS Elektronik&#8217;s <strong>industrial testing power<\/strong> solutions are designed for ATE integration. The EA-PSI series of programmable DC power supplies offers multiple interfaces (USB, Ethernet, analog), SCPI command support, and LabVIEW drivers, enabling seamless integration into automated test systems. The auto-ranging output stage provides flexibility to test different devices with a single power supply.<\/p>\n<p>For system integrators designing ATE systems, TPS provides comprehensive support, including power supply selection, integration guidance, and custom power system design. See the <a href=\"https:\/\/tps-elektronik.com\/en\/development-services-hardware-firmware-protocol\/\">Development Services for Hardware, Firmware, and Protocol<\/a> for more information.<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-18013\" src=\"https:\/\/tps-elektronik.com\/wp-content\/uploads\/2026\/09\/Industrial-Power-Supply-with-Remote-Sensing-for-ATE-Integration-3.jpg\" alt=\"Industrial Power Supply with Remote Sensing for ATE Integration Industrielles Netzteil mit Remote-Sensing-Funktion f\u00fcr die ATE-Integration\" width=\"1920\" height=\"1079\" \/><\/p>\n<\/section>\n<section id=\"remote-sensing\">\n<h2>4. Remote Sensing and Load Compensation<\/h2>\n<p>In test bench applications, the power supply is often located some distance from the device under test. The cables connecting the power supply to the DUT have resistance, and the current flowing through these cables causes a voltage drop. For a 1A load with 0.1\u03a9 of cable resistance, the voltage drop is 100mV\u2014significant for a 3.3V rail.<\/p>\n<p><strong>Remote sensing<\/strong> solves this problem by using a separate pair of sense wires to measure the voltage directly at the DUT. The power supply adjusts its output to compensate for the cable drop, ensuring that the DUT receives exactly the programmed voltage.<\/p>\n<p>TPS power supplies include remote sensing terminals as standard. For test bench applications, this capability is essential for:<\/p>\n<ul>\n<li><strong>Accurate voltage at the DUT:<\/strong> Ensuring that the device receives the specified voltage regardless of cable length<\/li>\n<li><strong>Repeatable measurements:<\/strong> Eliminating cable drop as a source of measurement variation<\/li>\n<li><strong>Long cable runs:<\/strong> Enabling the power supply to be located in a rack while the DUT is on a separate bench<\/li>\n<\/ul>\n<p>For <strong>calibration equipment power<\/strong> applications, remote sensing is particularly important. Calibration standards require precise, known voltages; any error introduced by cable drop compromises the calibration.<\/p>\n<p>The auto-ranging output stage of TPS power supplies supports constant voltage, constant current, constant power, and constant resistance modes with fast crossover, providing flexibility for diverse test applications. The built-in supervision features reduce test equipment requirements and eliminate the need for external monitoring hardware.<\/p>\n<\/section>\n<section id=\"tps-capabilities\">\n<h2>5.
