How to make fast and accurate power-integrity measurements
Today’s electronic devices with fast FPGAs, ASICs, and other ICs rely on ever-smaller power rail voltages with tight tolerances. Engineers who incorporate these ICs into their systems need to use oscilloscopes, probes, and measurement techniques that align with today’s tight voltage rail tolerances. … [Read More...] about How to make fast and accurate power-integrity measurements
Measurements verify power integrity
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 … [Read More...] about Measurements verify power integrity
Water-cooled probe injects disturbances onto power rails
The P2124 from Picotest lets you inject modulation signals onto your board's power rails for noise immunity testing. All circuits are susceptible to noise on their power rails. That's why filtering is so important. To test that susceptibility, you need a controlled disturbance where you can … [Read More...] about Water-cooled probe injects disturbances onto power rails
I’ve got the measurement blues again
Back from a three-year hiatus, I'm covering test and measurement again. This time, it's for EE World. I'm pleased to announce my return to the test-and-measurement community. For those of you who may not know, I covered T&M for several publications from 1992 to January 2020. In January 2020, … [Read More...] about I’ve got the measurement blues again
Software tests PCIe 6.0 on high-end oscilloscope
Teledyne LeCroy has released a beta version of software for automating serial-data analysis on PAM4 signals. Engineers can request a copy. By using PAM4 modulation, PCIe 6.0 doubles data rates to 64 GT/sec (256 Gb/sec when using an x16 configuration). The "secret sauce" in the doubling comes from … [Read More...] about Software tests PCIe 6.0 on high-end oscilloscope
The case for buying a used oscilloscope
Not all test labs need oscilloscopes sporting 1 GHz bandwidths and multi-million-point digital waveform recording. When the needs lean more toward the basic side, used scopes can sometimes fit the bill and do so economically. Here are a few points to consider before ponying up for a used … [Read More...] about The case for buying a used oscilloscope
New oscilloscopes feature super-fast 4.5 M acquisitions/sec update rate
The new R&S MXO 4 series oscilloscopes feature the world’s fastest real-time update rate of over 4.5 million acquisitions per second. Development engineers can now see more signal detail and infrequent events than with any other oscilloscope. The 12-bit ADC in the R&S MXO 4 series has 16 times the … [Read More...] about New oscilloscopes feature super-fast 4.5 M acquisitions/sec update rate

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 […]
