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 direction keys
and knob。
 The modulating waveform frequency ranges from 2mHz to 1MHz, and the
default value is 100Hz.
Note: when external modulation source is selected, this menu will be grayed out and
disabled.
To Set Phase Deviation
Phase deviation is the deviation of the modulating waveform phase relative to the
carrier waveform phase. Press PM Dev to set the PM phase deviation.
 Use the numeric keyboard or direction keys and knob to input the desired phase
value.
 The range of phase deviation is from 0° to 360° and the default is 90°.
When external modulation source is selected, the phase deviation is controlled by the
±5V signal level from the [CH1/Sync/Ext Mod/Trig/FSK] connector at the rear
panel. For example, if the phase deviation is set to 180°, +5V signal level
corresponds to a 180º phase variation. The lower the external signal level, the less
deviation would be generated.
