To Set the Phase Deviation
The phase deviation is the deviation of the phase of the modulating waveform
relative to that of the carrier waveform and the unit is rad.
Press Deviation to set the ØM phase deviation.
 Use the numeric keyboard or knob to input the desired phase value.
 For different carrier frequencies, the maximum phase deviations are different.
To Select the Modulation Waveform
Press Source to select "Int" modulation source; use the menu page up/down key
to open the 2/2 page of the menu; press Waveform to select "Sine" or
"Square" and the default is "Sine".
Note: When "Ext" modulation source is selected, this menu is grayed out and
disabled.
To Set the Modulation Frequency
Press Source to select "Int" modulation source; press Rate to set the modulation
frequency.
 Use the numeric keyboard or knob to input the desired frequency value.
 For sine waveforms, the range of the modulation frequency is from 10 Hz to 100
kHz.
 For square waveforms, the range of the modulation frequency is from 10 Hz to
20 kHz.
Note: When "Ext" modulation source is selected, this menu is grayed out and
disabled.
