For engineers working on high-power systems like motor drives, EV powertrains, or switching power supplies, accurate current measurement without breaking the circuit is a core requirement. Teledyne LeCroy introduced the CP1000 current probe at APEC 2026 to address that requirement. The CP1000 supports up to 1000 A rms continuous and peak currents up to 1400 […]
Oscilloscopes
Editorial Webinar April 16: Beyond bandwidth: how engineers should really choose an oscilloscope
Bandwidth is usually the first number engineers look at when evaluating an oscilloscope. It shouldn’t be the last. Today’s designs are more complex than ever. Signal frequencies are climbing, package sizes are shrinking, and the range of bus types and standards that engineers need to support continues to expand. A scope that checks the bandwidth […]
R&S MXO3 Oscilloscope for EMC measurements: part 1
Rohde & Schwarz recently announced the MXO3, a 1 GHz, 12-bit oscilloscope. The company sent a review unit. In this part, I found that it has some nice features for making EMC measurements, though it could use another. R&S sent me a model MXO38, the eight-channel version with built-in 50 MHz single-channel AWG and two […]
Noise generator substitutes for tracking generator
When your spectrum analyzer lacks a tracking generator, you can use a low-cost noise generator to characterize RF components. Here’s how. Low-cost spectrum analyzers often lack tracking generators, preventing you from having a signal source that tracks the analyzer’s frequency sweep. Not having a tracking generator can make some measurements difficult. You can, however, use […]
NI boosts PXI with controllers, chassis, and I/O
PXI continues to grow with an 18-slot chassis, system controllers, multifunction DAQ, and an oscilloscope. NI’s line of PXI-based test instrumentation has received a significant boost. Nearing 30 years old, PXI has become the standard for modular instrumentation in automated test for it boasts a thriving multi-vendor ecosystem. PXI originator NI has added an 18-slot […]
Make the most of oscilloscope triggering: part 1
Learning the basics of oscilloscope triggers can help you leverage advanced features. In an earlier series, we discussed how the oscilloscope has evolved over the past three-quarters of a century. We noted that the basic horizontal and vertical controls remain functionally similar, but today’s digital oscilloscopes offer many features, including waveform math functions, that go […]
Oscilloscope software automates DisplayPort 2.1 PHY testing
QPHY 2 software lets you test DisplayPort 2.1 links for compliance to industry standards Engineers designing DisplayPort 2.1 into devices need a way to verify compliance with standards and that the interface will interoperate with other devices. This involves viewing physical-layer (PHY) eye diagrams at both transmitters and receivers. DisplayPort 2.1 PHY compliance test software […]
USB oscilloscope software adds waveform overlays and other new features
Picoscope 7.2 makes troubleshooting easier by highlighting decision points on waveforms. New features include: Waveform overlays, which let you see differences in captured signals, helping you identify glitches on other intermittent occurrences; Measurement Indicators: the software places visual markers on waveforms, which highlight the points where it measures parameters such as rise time and frequency; […]
Locate ESD sources using an oscilloscope and two antennas
The key to identifying the location of an ESD source is by measuring the time of arrival between the two antennas. ESD discharges are tough to locate because they don’t occur periodically. Rather, they occur intermittently. I earlier wrote an application note on how to use an oscilloscope to trace the path of ESD current […]
Tektronix event highlights precision measurements
At “Precision Unveiled,” Tektronix gave attendees a look at the future and displayed some current test equipment. Raleigh, NC, October 28, 2025 — Tektronix, well known for oscilloscopes and more recently power sources and power measurements through its acquisitions of Keithley and EA Elektro Automatic, hosted an event at the North Carolina Museum of Art.
