I want to check the SNR through VisualAnalog by applying a modulated signal to the AD9652 EVAL.
As shown below, I tried to check the SNR by applying a modulated signal with 20MHz Bandwidth, and it showed approximately -13.8 dB.
I think this is the calculated value with the settings for the CW signal. So I guess that's not an exact value.
I wonder if I can change the number of Bins of "Fund" in "FFT Analysis Settings" to accurately measure the SNR for the modulated signal.
If so, how can I calculate the number of those bins? Or is there any other way I can get the SNR for the modulated signal via VisualAnalog?
