hi sivakumar, for low sample rate FFT's (where the FPGA clock = sample rate), i suggest you consider: fft_biplex_real_2x <https://casper-toolflow.readthedocs.io/en/stable/src/blockdocs/Fft_biplex_real_2x.html> (Real-sampled Biplex FFT, with Output Demuxed by 2) fft_biplex_real_4x <https://casper-toolflow.readthedocs.io/en/stable/src/blockdocs/Fft_biplex_real_4x.html> (Real-sampled Biplex FFT, with Output Demuxed by 4)
the various casper FFT's are listed here: https://casper-toolflow.readthedocs.io/en/stable/blockdocumentation.html what is the 32 input ADC board you are trying to calibrate ? is this the board designed by larry dedarrio for the LWA ? best wishes, dan On Mon, Mar 18, 2024 at 7:53 PM Sivasankar <sivasiva8...@gmail.com> wrote: > Dear Caspers, > Currently I am facing an issue with 32 ADC channel calibration > with ROACH2 rev2 board.
