Regarding the TX bandwidth setting & Cali of AD9361

Question asked by CDFUTURE on May 27, 2017

Hi, ADI friend:

I'm reading the calibration guide of AD9361 and find:

1. Before we do the RX bb analog filter cali, we need to write the analog Bandwidth parameter to register 0X1FB&0X1FC. 

2. But this step does not need for TX bb analog filter cali. (Both in the no-os code & script )

3. So my qustion is why we do not need write Bandwidth parameter for TX bb filter calibration?
