Just a quick video on another possible way to use your RIGOL DSA815 RF Spectrum Analyzer. As I mentioned in the video, the output level of the RF from the tracking generator isnt ruler flat so it may not be the most accurate RF signal source amplitude wise. You could always measure the out put on the Analyzer at the desired frequency and use that as a reference. Normalizing wont do any good as that is only compensation on the "receive" side of the analyzer as far as I know . Could still be useful for troubleshooting and seeing if a receiver is at least close to the correct RF input sensitivity. Thanks for watching. 73 from Randy, N2CUA
