The ADRV9002 RX signal chain includes a DDC with a mixer and NCO that can be used to tune the desired bandwidth to an offset from the LO frequency. I have seen this working with the TES software at a 48kHz sample rate - I can tune an offset frequency so that the LO center spur/notch filter is no longer in-band, as well as the image spur. This is a very nice feature.
In the ADRV9001 user guide, it mentions that this functionality is for NB (<1MHz bandwidth) applications where the requirements are more stringent than WB applications. It also says that the frequency offset can be tuned up to 21MHz off from the LO.
We typically have WB applications (full 40MHz bandwidth). For us, the notch filter in the center of the band is a problem. Also, the image spur is often what limits the performance. If the NCO supports up to a 21MHz offset, this should theoretically be enough to shift the LO center spur/notch filter out of our 40MHz band of interest. I have tried to do this in TES but it didn't work.
Does the ADRV9002 support shifting the desired band when running in a WB application? Is it just a case that it is not supported in TES yet? Or is there some other limitation which prevents this functionality from being used in WB applications (>1MHz bandwidth)?
