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 ?

If it did TDR, you could sell bundles of them to PCB houses, and to
engineers and QC people who care about trace impedances. Especially if
it were cheap and interfaced to a PC, so it could document pcb test
coupons.
I'd design the fast stuff if somebody else handles the USB part and
the PC software. I have a slick deconvolution algorithm that would run
on the pc side and really beautify the TDR response.
