I am currently working on ADRV9002 based application with the following requirements
1) Acquire 10MHz I/Q data in Rx only mode
2) Utilize Low IF mode to reject LO leakages and improve image rejection
And to configure the transceiver, I am using TES GUI in offline mode to arrive at the necessary device configuration. I would like to clarify the following
a) Does support for Rx only mode configuration available in TES GUI for ADRV9002. What should be setting for Duplex field (in Device configuration tab >> Device) for Rx only configuration. I am presently using TDD setting for Duplex field with Tx disabled (to operate in Rx only mode). Is it valid?
b) How to configure the LO offset frequency for Low IF mode of ADRV9002 operation in TES GUI. I would like to operate the transceiver for 10MHz signal bandwidth with 10MHz IF offset, since the transceiver supports 40MHz wide IF (+/-20MHz). So the signal seen by the ADCs will lie in the range of +5MHz to +15MHz before digital down conversion and by using the NCO frequency of 10MHz the signal of interest can be captured in low IF mode.
Please do let me know, how to carryout the low IF configuration for the application mentioned above. Where the Low IF offset frequency can be entered.
c) Is there a method available to generate ARM image as a file, similar to generate stream image option in TES GUI. I see the ARM image generated as an initialized array in generated C code. Will the ARM image change as per the device configuration ? Under what circumstances do I need to replace the ARM image ?
