Gw Instek GDS2204E (200MHz 4 channel DSO) review
nctnico:
I have not tried but I'm sure the span will be the same because 1Gs/s is the maximum samplerate either way.

Stretching the rope, I wish Santa could make FRA APP work with an external function generator so it could run on the GDS scopes.

It would be nice if the FRA app were usable on the units *with* AWGs. A scan from 13-14 MHz at the maximum sampling of 90 samples per decade produces two points. So no way to find the resonances of a crystal with that.
I was able to sync it with a 33622A but not consistently. Despite several hours of fiddling, I was never able to get the series response of a crystal such as an 8560A SA w/ TG will produce. It's probably because the various operations are not operating in the same clock domains.
Mortymore:
Oh well!!... An SDS1104X-E to marry with the SDG1032X would solve the Bode plot problem ::)

Yep.
SDG1032X -- Xtal---SDS1104X-E
Span 5kHz
Span 500Hz

You should be able to do this if you have a generator which can step through a range of frequencies with a certain dwell time. Most RF generators support this.
