The tinySA is used as signal generator and a spectrum analyzer in combination with an old vacuum tube AM/FM receiver.
Both AM and FM signal generation and reception is demonstrated and, using one tinySA as signal generator and a second tinySA as spectrum analyzer, the various 455kHz and 10.7MHz IF stages are probed. Also the probing of the LO is demonstrated.
The AM IF signal levels were lower than the FM IF levels because I forgot to connect the tinySA back to the AM antenna input when probing the AM IF
