Andy I would be interested in your findings on locking the sound card to a master reference. All of the receiving and transmitting stuff here is tied to GPS so the sound card is the weak link in the
Thanks for all your responses on Soundcard mods. There seem to be so many variations, the easist way, the route we'll probably follow, is to get a separate data collection card rather than trying to
Hello Andy and group, Instead of using the 1kHz reference signal as a sample clock for the soundcard (which may be a *very* tricky job), why not use 1kHz as a reference to determine the 'true' sample

Hi Andy, As a couple of the other guys have pointed out, it depends on the soundcard. Assuming it does have an onboard crystal or brick to determine samplerates, yes, of course one can take liberties
Hello Andy, if you (your company) can spend some dimes on it I would strongly recommend to use a good ADC card. There is a lot of plug-in cards available, but we tend to use Keithley cards. For a rec
Has anyone tried changing the clock source on a Soundcard for a different frequency ? For a job here at work we need to sample more accurately than the usual crystal oscillator (does this sound famil
