Modulating Waveform Frequency
The instrument accepts an internal or external modulation source. The external modulation input has a -3dB band-
width of 100 kHz.
Modulating frequency (internal): 1 µHz to 30 MHz, default 10 Hz.

Phase Deviation
The phase deviation setting represents the peak variation in phase of the modulated waveform from the carrier wave-
form. The phase deviation can be set from 0 to 360 degrees (default 180).
