Field Descriptions
AFGen1 To
This Audio Frequency Generator control is used to set two values:
• The upper field determines whether the AF signal modulates the RF Generator or is out-
put through the AUDIO OUT connector.
• The lower field sets the amplitude (including Off). The AUDIO OUT level is set either
in volts rms (across a low-impedance output) or dBm, mW, or W across a 600-ohm load
(mW is selected by pressing [SHIFT], [ENTER]).
Operating Considerations
The upper field is a priority control field. Accessing the RX TEST or TX TEST
screen overrides any changes made to this field in other screens.

AFGen2 To
This Audio Frequency Generator control is used to set two values:
• The upper field determines whether the AF signal modulates the RF Generator, or is
output through the AUDIO OUT connector.
• The lower field sets the amplitude (including Off). The AUDIO OUT level is always
in volts rms for standard sinewave operation across a low-impedance output.
If the signaling option is installed, the sinewave can be set in units of rms or peak.
This is done in the Sine Units field for the Function Generator. When non-
sinewave waveforms are used, or if the upper field is set to AM or FM, the level is
always expressed as a peak value.
