Can ADRV9002 use different Lo frequencies in Channel1 and Channel2

Category: Software
Product Number: ZCU102 + ADRV9002XBCZ
Software Version: 2021-07-28-ADI-Kuiper-full.img

Our goal : 

1. LO of TX1 and RX1 operates at 700MHz;

2. LO of TX2 and RX2 operates at 2.4GHz;

3. IQ data flow like this:  RX1 -> IQ data -> TX2, RX2 -> IQ data -> TX1;

In the first step, I did such an experiment, but failed :

First. 500kHz sine IQ is selected for TX1 data, and LO of TX1 is configured to 700MHz; (At this time, the spectrum analyzer observes that TX1 and TX2 are both 700.5MHz signals)

Second. 100kHz sine IQ is selected for TX2 data, and LO of TX2 is configured to 2.4GHz; (At this time, the spectrum analyzer observes that TX1 and TX2 are both 2400.1MHz signals)

Third, I read back the values of each register. At this time, the LO of TX1 is still 700MHz, and the LO of TX2 is still 2.4GHz.

What are the reasons for my problems?

In addition, is it possible to achieve our goal through adrv9002?

Thank you very much!!!
