To Set Modulating Waveform Frequency


When internal modulation source is selected, press PM_Freq to set the modulating
waveform frequency.
 Input the desired frequency value using the numeric keyboard or knob.
 The modulating waveform frequency ranges from 2 mHz to 50 kHz, and the

default value is 100 Hz.


Note: This menu will be grayed out and disabled when external modulation source is
selected.

To Set Phase Deviation


Press Deviation to set the deviation of the modulating waveform phase relative to
the carrier waveform phase.
 Input the desired phase using the numeric keyboard or knob.
 The phase deviation ranges from 0º to 360º.

When external source is selected, phase deviation is controlled by the ±6 V signal
level of the Mod in/I connector at the rear panel. For example, if the phase deviation is
set as 180º, +6 V signal level corresponds to a 180º phase change. Lower external
signal level generates less deviation.
