Hi All :
For FPGA chip on ZCU111 board,I want to ask some questions:
1.If my signal bandwidth is 500MHz, and sampling rate is 4GHz.
Can I set RFSoC central frequency to 1/2 fs (2G Mhz)?
Due to the signal is across zone 1 and zone 2 ,The frequency range I can set is (2G -1/2*BW)
i.e. 0Mhz~ 1750Mhz and 2250Mhz~4000Mhz ?
2. The calibration mode 2 is around 1/2 fs +- 10%(1800Mhz~ 2200Mhz) ,
So my 500Mhz signal can't locate cross two calibration mode?
i.e. I just can set central frequency to 0Mhz~(1800-250)MHz?
Thanks a lot~
I am not sure i follow this. It is not clear what you mean by setting the central frequency.
you have the Fs = 4Ghz and you want to sample a carrier located at 2Ghz that is 500Mhz wide.
This can't work, you'll get the upper half of the carrier folded back on the lower 250Mhz.
