Custom OFDM SNR (or VSA Rx sensitivity)

Question asked by np on Nov 4, 2015

I am using a VSA 89601B running on a PXA N9030A. I have created a custom OFDM signal and I am receiving and demodulating it through the VSA. Then I am using some post processing to get the Bit error rate (BER) of the received signal.

Although I am able to get the results on the screen and after the post processing... something really important is missing. The SNR of the signal, so as to understand if what I am getting on the BER follows the theory or not.

My signal has a bandwidth of 100MHz and it is centered around 1.5GHz.

Is there a way to get this information from the VSA itself? Or is there a certain "receiver sensitivity" metric for the VSA so as to be able to demodulate?
