Oscilloscope software automates automotive ASA-ML serial link tests

June 27, 2025 By Martin Rowe Leave a Comment

Teledyne LeCroy ASA-ML oscilloscope test software

QPHY2-ASA software from Teledyne LeCroy lets you perform physical-layer tests on ASA-ML v1.1 devices. SerDes devices transfer data from sensors and cameras to an in-vehicle processing unit, which then sends instructions to the motion systems that drive autonomous vehicles. Teledyne LeCroy has released the QPHY2-ASA oscilloscope software, which automates testing of the Automotive Serdes Alliance […]

APEC 2025 test equipment: oscilloscopes and probes

March 24, 2025 By Martin Rowe Leave a Comment

oscilloscope and probes in power electronics

Oscilloscopes and probes play a vital role for engineers designing and testing power electronics. Delivering electrical power to analog and digital circuits and systems is more than just DC measurements. That’s because nearly all power-converter circuits use switching techniques to maximize efficiency. Silicon carbide (SiC and gallium nitride (GaN) transistors, with their higher voltage and […]

APEC 2024: Test equipment

March 14, 2024 By Martin Rowe Leave a Comment

Test equipment is everywhere. Every trade show has it regardless of the focus. Power is no exception. At APEC 2024, EE World visited several booths displaying test equipment: meters, oscilloscopes, source-measure units (SMUs), bench power supplies, and electronic loads. The photos and videos below highlight what we saw, presented in alphabetical order by company. In […]

AOC 2023: Exhibits show the latest in military wireless

January 4, 2024 By Martin Rowe Leave a Comment

Washington — The Association of Old Crows (AOC) held its 60th annual convention in Washington during the week of December 11, 2023. EE World was there on December 12. Here is some of what we saw in the exhibit hall. AOC is a defense-oriented conference that focuses on military wireless communications. In addition to product […]

12-bit oscilloscope reaches 65 GHz, tests high-speed links

September 5, 2023 By Martin Rowe Leave a Comment

The WaveMaster 8000HD series from Teledyne LeCroy goes where no 12-bit oscilloscope has gone before. Serial digital data streams never stop reaching for higher data rates. Buses such as PCIe Gen 6 (64 Gtransfers/sec) and USB4 V2 (80 Gb/sec) have gone to PAM4 and PAM3 modulation, respectively, to reach their current data rates. Two-level modulation […]

What is jitter and what can I do about it (part 2 of 2)?

June 21, 2023 By Rick Nelson Leave a Comment

Operations on acquired jitter data help quantify jitter values. Part 1 of this article described the oscilloscope eye diagram and unit interval (UI) and focused on a single ideal rising edge with 28 additional edges representing some degree of jitter (Figure 1). We determined the peak-to-peak jitter to be 15 ps, based on the edges […]

What is jitter and what can I do about it (part 1 of 2)?

June 14, 2023 By Rick Nelson Leave a Comment

Measuring and quantifying jitter are the first steps toward controlling it. Jitter is a measure of the timing performance of a digital data stream such as Ethernet, USB, PCIe, or HDMI. It defines when data transitions occur in relation to an ideal waveform. Excess jitter can lead to signal-integrity problems that result in high bit-error […]

Measurements verify power integrity

May 22, 2023 By Ken Johnson, Teledyne LeCroy Leave a Comment

Engineers should measure and analyze power integrity on the power and ground planes of a board’s power distribution network. Understanding power integrity is crucial when evaluating circuit power quality because it has a direct influence on performance. Power integrity is a subset of signal integrity, whose assessment ensures that signals have suitable amplitude, rise time, […]

PCI Express 5.0 interposer works with protocol analyzers

August 3, 2022 By Lee Teschler Leave a Comment

teledyne lecroy

A PCI Express 5.0 Mini Cool Edge IO (MCIO) interposer works in combination with Teledyne LeCroy’s Summit family of PCI Express 5.0 protocol analyzers. The new interposer enables engineers to test products that incorporate card edge connectors or cabled connector assemblies that utilize the MCIO mechanical connector with PCIe 5.0, NVM Express (NVMe) or Compute […]
