Automated test equipment (ATE) ranges from one computer driving two bench instruments to a production rack with switching, fixtures, safety interlocks and pass/fail software. The scale follows the test, not a fixed template. For engineering work and small batch runs,...

Different battery tests require different instruments. Measuring capacity, analysing device current, emulating charge levels and diagnosing fast electrical events are separate tasks. A practical bench may therefore combine electronic loads, SMUs, DC power supplies, DAQ systems and oscilloscopes. The Keysight...

A power supply ripple measurement can be distorted by the probe connection, the oscilloscope settings and electrical noise around the bench. The waveform on screen may differ from the ripple and noise actually present on the DC rail. Engineers often...

An electronic load is a versatile, programmable instrument designed to sink controlled current, hold specified voltages, emulate precise resistance, or absorb constant power from a device under test (DUT).  Unlike static resistive loads, selecting the right electronic load depends on...

Choosing a DC power supply involves more than matching a voltage and current rating.  The right Keysight power instruments must deliver enough power for the device under test (DUT), maintain a stable output during load changes, meet your noise requirements...

An oscilloscope and a spectrum analyzer can both help engineers examine electrical signals, but they present those signals from different perspectives.  An oscilloscope primarily displays voltage over time, making it the preferred instrument for analysing waveform shape, timing, rise time,...

Every purchase request that says "I need a signal generator" and nothing else creates the same problem. Procurement can't quote it. The vendor can't spec it. And the engineer who wrote it probably meant one of three different instruments. The...

You are looking at two oscilloscopes with identical bandwidth ratings. One costs significantly more than the other. The datasheet for both shows the same maximum sampling rate.  You are not sure which specification actually matters for your application, and what...

Whether you're developing electronic products, validating circuit performance or troubleshooting industrial equipment, a digital multimeter (DMM) is one of the most frequently used test instruments. It provides accurate measurements of voltage, current, resistance, continuity and other electrical parameters, making it...

When using your smartphone or trying to get a stable internet connection, have you ever wondered what makes these technologies work? Behind them are radio-frequency (RF) signals, which make wireless communication possible. But for wireless devices to perform well, those...
