Whats the standard way to perform and capture RSSI and throughput measurements?

Hi everyone! Thanks to everyone and especially @RightHalfPlane for getting me through the growing pains. I learned a bunch and found out how awesome RF can be.

Anyways, I was curious as to what is the standard in measuring RSSI and throughput in terms of kpbs/mbps and having it be recorded in a CSV file to be used for graphing later?

Right now I am trying the Log Power FFT and the Probe Rate. When it comes to the Log Power FFT how would one decipher it? , for the Probe Rate it gives me a Item/sample per second how does one translate this to kbps/mbps?

Thank you and any input is appreciated
