Re: [casper] ADC ROACH2 clock signal, or Function generator

With response to the previous question regarding clock source: Dan, do you find a difference in feeding of the clock source, be it a sine wave -or- a square wave ? For example, do you see any increase in S/N or sensitivity when fed by a square wave as opposed to a sine, and when clocking is fed

Re: [casper] ADC ROACH2 clock signal, or Function generator

Hi Dan I appreciate your recommendation, now I understand better, I think very expensive equipment is not necessary. Well, I would like to have my portable system and I didn't know which generator to use as a clock signal. Cheers Javier Ulloa El mar, 1 dic 2020 a las 13:52, Dan Werthimer ()

Re: [casper] ADC ROACH2 clock signal, or Function generator

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:

[casper] ADC ROACH2 clock signal, or Function generator

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

Re: [casper] Wideband FFT using Xilinx blocks as primitives

Hi all, Sorry for the late follow-up. I wanted to add to Jeb's comment: The FFT we are using on the RFSoC is 16x4096 meaning it processes 16 complex samples each clock and runs at 512 MHz. We used the Xilinx SSR FFT available in System Generator versions 2019.1+. It can be configured for a
