I am interested in buying a device that measures the SINAD of the audio signal(FM signal) that I receive from PC. Here is the setup:
Signal generator (generating 1kHz FM signal ) $\rightarrow$ attenuator $\rightarrow$ HackRF connected to PC with SDR#
When we receive a 1kHz FM signal generated by the signal generator at the HackRF (which is connected to PC), we get an audio tone from the PC as output. I am interested in measuring the audio quality of FM tone that we receive at hackrf (connected to PC with SDR# support).
I know that for some signal generators, there is a separate port for measuring SINAD. The signal generator that I have does not have the capability to measure the SINAD. So, if there are any other devices that can help me measure this SINAD, please let me know.
Note: Sorry, I asked the same question without registering in dsp.stackexchanege (Any recommendations for buying SINAD measuring equipment?). I was unable to edit the question. So created a new one here.
