To Set the Frequency Deviation
The frequency deviation is the deviation of the frequency of the modulating
waveform relative to that of the carrier waveform and the unit is Hz.
Press FM/øM  Deviation to set the FM frequency deviation.
 Use the numeric keyboard or knob to input the desired frequency value.
 The different RF frequency setting corresponds to different maximum frequency
deviation.
To Select the Modulation Waveform
Press FM/øM  Source to select “Int” or “Int & Ext” modulation source; use the
page up/down key
to open the 2/2 menu page and 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 FM/øM  Source to select “Int” or “Int & Ext” modulation source; press
Rate to set the frequency of the modulating waveform.
 Use the numeric keyboard or knob to input the desired frequency value.
 For sine waveforms, the range of the modulation frequency is from 100 mHz to 1
MHz.
 For square waveforms, the range of the modulation frequency is from 100 mHz
to 20 kHz.
NOTE: When “Ext” modulation source is selected, this menu is grayed out and
disabled.
