to the RF IN/OUT o r ANT IN connectors .
•Audio In for a signal connected to the AUDIO IN connector.
•Radio Int for a signal connected to the optional rear panel Radio Inter-
face connector.
•Ext Mod for a signal connected to the rear panel MODULATION IN-
PUT connector.
•Mic Mod for a signal connected to the MIC/ACC connector “MIC” pin.
•FM Mod for the FM modulated audio from the RF Gen section.
•AM Mod for the AM modulated audio from the RF Gen section.
•Audio Out for the signal present at the AUDIO OUT connector
5. Select from the Scope To field’s list of choices where in t he AF Analyzer’s
circuitry the signal is routed to the Oscilloscope.
NOTE: All choices except Input are capa citiv e couple d. Use Input if the sign al bein g
measured is ≤1Hz.
•Input to route the audio to the Oscilloscope without being processed.
•Filters to route the audio to the Oscilloscope after pa ssing through Fil-
ters #1 and #2.
•De-emp to route the audio to the Oscilloscope after passing through F il-
ters #1 and #2, and the De-Emphasis circuitry.
•Notch to route the audio to the Oscilloscope after passing through Fil-
ters #1 and #2, the De-Emphasis circuitry, and Notch circuitry.
