12-bit oscilloscope reaches 65 GHz, tests high-speed links
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 … [Read More...] about 12-bit oscilloscope reaches 65 GHz, tests high-speed links
What specialist software is available for USB oscilloscopes: Part 2?
This FAQ looks at software that can synchronize multiple oscilloscopes, perform mathematical functions, and transform a basic USB oscilloscope into multiple instruments. A USB oscilloscope consists of signal capture and conditioning electronics, a personal computer (PC) that can be a laptop, … [Read More...] about What specialist software is available for USB oscilloscopes: Part 2?
What specialist software is available for USB oscilloscopes: Part 1?
USB oscilloscopes capture analog and digital signals. Through software, engineers can analyze protocols and logic signals. By adding a D/A converter, a USB oscilloscope can also become a waveform generator. A USB oscilloscope consists of the signal capture and conditioning electronics package, a … [Read More...] about What specialist software is available for USB oscilloscopes: Part 1?
What’s a USB oscilloscope?
By connecting to a computer, a USB oscilloscope lets engineers offload screens and compute-intensive functions to the host, which reduces needed bench space and brings portability. Oscilloscopes are sometimes grouped into three types, benchtop, portable, and USB. The first two types are … [Read More...] about What’s a USB oscilloscope?
What is PCIe gen 6 and how do I test it? Part 2
PAM4 modulation boosts throughput but adds test challenges. Part 1 of this two-part series described the evolution of the PCI Express (PCIe) standard, including the move from non-return-to-zero (NRZ) signaling in PCIe 5 to four-level pulse-amplitude modulation (PAM4) signaling in PCIe 6. What … [Read More...] about What is PCIe gen 6 and how do I test it? Part 2

What is the importance of resolution in an oscilloscope?
When looking at the oscilloscope feature of a multi-instrument device or when comparing two benchtop oscilloscopes, the first specifications that we look at are the bandwidth and sample rate. While these are incredibly important specs, often most design work is done well within the limits of most products and the more critical specification to consider is resolution. Did you know that while most […]
