You can get the HP3562A used for under a grand. It is 14 bits and 100khz. It has GPIB to offload the data.

Should note it's 100kHz bandwidth; sampling is faster. Of course, it's also BIG and HEAVY (and if something goes wrong inside, it may not be easy to fix).

It has a self-check, which makes the used purchase safer. The big advantage to the 3562 is the synchromized sine source. No edge effects, i.e. windowing errors. Big? You bet. ;-)

Big and noisy (fan) but excellent. The 3562A has service manuals available but I couldn't find the 3563A ones. -- Thanks, Fred.

Gee, Fred, I'm curious where you found a 16 bit 3563A ... ;-) Cheers, Tom |
