to the RF IN/OUT or 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 the AF Analyzer’s
circuitry the signal is routed to the Oscilloscope.
NOTE: All choices except Input are capacitive coupled. Use Input if the signal being
measured is ≤1Hz.
• Input to route the audio to the Oscilloscope without being processed.
• Filters to route the audio to the Oscilloscope after passing through Fil-
ters #1 and #2.
• De-emp to route the audio to the Oscilloscope after passing through Fil-
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.
6. Select the SCOPE screen.
7. Select the CONTROLS field.
8. Continue the measurement by selecting a control screen from the list of
choices and referring to the following:
• see "Measurements Using the Main Control Fields:" on page 238.
• see "Measurement Using the Trigger Control Fields:" on page 239.
• see "Measurements Using the Marker Control Fields:" on page
