To Set FM Waveform
The modulated waveform consists of two parts: the Carrier Waveform and the
Modulating Waveform. In FM, the Frequency of the Carrier Waveform varies with the
instantaneous voltage of the modulating waveform.
Carrier Waveform used in FM can be set through the Sine, Square, Ramp, Arb button
on the front panel.
Press Mod Type FM, enter the following interface.
