Hi guys !
I'm looking for a solution to measure PCBs, power supply decoupling performance, input impedance of stuff that has inputs, etc... I've got a 60 MHz network analyzer, works great, but I'd like to go a bit higher in frequency, without spending megabucks. And suddenly, this post from 2008 :
So, if someone here has interest in designing the fast stuff (or just throwing some schematics), I'd gladly volunteer for the rest (usb, micro, adc, software, gui, etc).
Basically a board which :
- outputs a fast pulse or edge
- has an input with a sampler running synchronous to the output, with a delay sweep
- ADC, usb, pc, display
With a Cypress FX2 ez-usb chip, streaming USB2 at full bandwidth is simple, I've got a board with that running from a previous project.
Anyone interested ?
