Title: High speed pulse generator
Post by: ezalys on May 13, 2022, 04:38:13 pm
Does anyone know of a pulse generator that provides variable length pulses with a minimum of 50 picoseconds? The PSPL10070A went down to 100 ps, but is no longer available. Is there a modern alternative or are all the T&M companies just going to try and sell me an AWG?

Just bumping this. 100 ps I should say could be acceptable. Highland technology seems to make something around 100 ps, but I'm shopping around.

Might be worth looking at Highland Technology http://www.highlandtechnology.com/categories/digital_delay_generators.shtml (http://www.highlandtechnology.com/categories/digital_delay_generators.shtml)

This one's minimum pulse width is 300 ps (https://www.activetechnologies.it/products/signal-generators/pulse-generators/pg-1000/), but it will do a <70ps rise time for a 5V pulse.

This Berkeley Nucleonics Model (https://www.berkeleynucleonics.com/model-765-800-mhz-fast-rise-time-pulse-generator) appears to be a repacked version of the Active Technologies Generator (https://www.activetechnologies.it/products/signal-generators/pulse-generators/pg-1000/).

A 50 ps pulse is pretty short.  What's the application?
