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 FM/øM Deviation to set the
Φ
M phase deviation.
Use the numeric keyboard or knob to input the desired phase value.
The different RF frequency setting corresponds to different maximum phase
deviation.
To Select the Modulation Waveform
Press FM/øM Source to select Intor Int & Ext” modulation source; use the
page up/down key to open the 2/2 menu page and press Waveform to select
Sineor Squareand the default is Sine.
NOTE: When Extmodulation source is selected, this menu is grayed out and
disabled.
To Set the Modulation Frequency
Press FM/øM Source to select Intor Int & Extmodulation 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 Extmodulation source is selected, this menu is grayed out and
disabled.
