Typical Tx / Rx EVM capabilities of RSA500X

Quote from hexium on 12/08/2023, 23:34Can you please provide an indication of the typical Tx / Rx EVM capabilities of RSA500X?
When connected to a Keysight Signal Generator and Spectrum Analyzer, I am measuring values in the region of -38 dB to -39 dB. Can you confirm that there are close to the typical values or is even better performance possible? To be honest I was expecting the Tx EVM to be even better (< -40 dB).
Thank you.

I tried tweaking all configuration parameters but did not manage to get anything better than -39 dB. Any specific suggestions?
Thank you!
