Basic FM Receiver Testing Setup
Refer to figure 4-2. Connect the analyzer's RF
I/O port to the radio antenna connector. Connect
the radio audio output to VERT/SINAD port of
the analyzer.
CAUTION
With some radios, grounding the speaker
leads will damage the audio circuitry. Use
isolation techniques on these radios.
