I'm trying to set analog LPF bandwidth by using rxProfile->rxBbf3dBCorner_kHz = 50000; however, it seems not to applied(frequency response still the same with the bandwidth = 100MHz). What is right way to set this bandwidth?
You need to generate a profile with filter wizard and Load it in TES GUI. You can test results in GUI. If it looks good you can generate a 'C' script which will have these values initialized properly.
I think that will work but not what I want to ask.
My question is "Can user change the LPF/analog filter bandwidth ONLY, without going thru generate a whole new profile? or what is the requirement to change the LPF/ analog filter on AD9371?"
Analog filter BW is decided by the actual BB BW requirement.
The roll-off in analog is compensated in digital while generating FIR co-efficient, this is the reason we recommend to use profile generator. Also profile generator will take care of all the internal clock dividers and ADC related config.
So my understanding is that we can not change Analog filter BW without going through the profile generator. Is that correct?
Yes your understanding is correct.
