My Rhode and Schwarz SMG 100kHz to 1GHz signal generator ist kaput, it is a not-signal geneator, it has gone to meet its maker; etc etc...
To be precise, the controller card has died, and although I have the manual and have sort of looked at it, really can't be bothered faffing any more , bearing in mind :
a) The fault is not simple PSU related; is also not cured by wobbling things, and I don't have the extender cards for proper hot-testing.
b) All the RF signal generator functions can be done with an LMX2541 or AD9852 DDS and an attenuator - all to hand here.
c) Any modulation it could generate can probably be done in a PC with soundcard and upconverter.
Is it worth anything (a guarded, roundabout way of saying, anyone interested) ?
or... Is it worth more as the sum of its parts if I rip the good bits out, like the programmable attenuator (pulse relay switched, 5dB steps) and the I/Q rotary encoder, then scrap the rest ? Can't think what else inside is worth salvaging.
