The path toward PAM-4 for 56-Gb/s channels and 400-Gb/s Ethernet is opening up, driven by multidimensional packaging and the need to optimize the installed fiber networks.
Getting the job done right means making design tradeoffs and spending your time wisely—sometimes you can save time by taking the easy road, sometimes not.
Though often comingled, jitter and noise are two completely different effects—gaining a better understanding of them can lead to more effective high-speed signal analysis.
This article pulls back the curtain a bit on the trigger system, one of the most commonly used but least-understood subsystems in real-time oscilloscopes.
Zone triggering is an oscilloscope technology that complements traditional scope triggering, helping to isolate events when hardware-based triggers fall short.
