RSSI Measurements

I performed RSSI measurements on AD-FMCOMMS3-EBZ board over frequency (800 MHz to 2.4 GHz) and dynamic range with an overall good accuracy. But in some points I have reached a much more precise result with setting the gain manually (in most cases lower than auto gain setting). I think that could be tuned via thresholds?


Another point is the actual very high third order harmonic while generating a test tone (both via the GUI and FPGA).

I have seen values up to 10dBc.

Is there a way to improve the auto calibration values with additional manual calibration steps?


Waiting for your kind reply.
