hi javier, most casper ADC boards want a 0dBm sine wave. square wave is fine too. with frequency at the adc sample rate, or perhaps 1/2 sample rate if the ADC is interleaved.
i like the small ~$500 synthesizers from DS instruments: https://www.dsinstruments.com/store/products/category/rf-signal-generators/ for a less expensive synth, i like this $100 synth: https://www.aliexpress.com/item/32723868163.html for a synth that always powers up to a frequency stored in it's flash, (eg: for an instrument, not lab bench use) many casper people use valon technologies synths. eg: https://www.valonrf.com/frequency-synthesizer-6ghz.html best wishes, dan Dan Werthimer Marilyn and Watson Alberts Chair Astronomy Dept and Space Sciences Lab University of California, Berkeley On Tue, Dec 1, 2020 at 11:36 AM luis javier Ulloa <ulloa.200921...@gmail.com> wrote: > Hello everyone, I hope you are well. > I am working with a ROACH2 and I had a question, what clock signal do you > use for your ADC, and I would like to know if you know of any signal > generator that is portable? > best regards > Javier Ulloa > > -- > You received this message because you are subscribed to the Google Groups " > casper@lists.berkeley.edu" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to casper+unsubscr...@lists.berkeley.edu. > To view this discussion on the web visit > https://groups.google.com/a/lists.berkeley.edu/d/msgid/casper/5b03334e-61d8-4333-bd20-fa53fc3cffc6n%40lists.berkeley.edu > <https://groups.google.com/a/lists.berkeley.edu/d/msgid/casper/5b03334e-61d8-4333-bd20-fa53fc3cffc6n%40lists.berkeley.edu?utm_medium=email&utm_source=footer> > . > -- You received this message because you are subscribed to the Google Groups "casper@lists.berkeley.edu" group.
