Frequency Modulation (FM)
For frequency modulation (FM), the frequency of the carrier waveform varies with
the instantaneous voltage of the modulating waveform.
To Select FM Modulation
Press Menu

Modulation

"FM" to enable the FM function. When Modulation
is enabled, Sweep or Burst will be automatically disabled (if enabled currently). Tap
the icon
at the upper-right corner of the interface (when Sine is selected as the
carrier waveform) to view and set the parameters of the current carrier waveform.
Tap the icon
at the upper-right corner of the interface again to go back to the
current modulation parameter interface.
To Select the Carrier Waveform
FM carrier waveform could be Sine, Square, Ramp, or Arbitrary waveform. The
default is Sine.

Press Menu

Continuous to select the desired carrier waveform.

Pulse, Noise, Harmonic, Dual-tone, and DC could not be used as carrier
waveform.
To Set Carrier Waveform Parameters
The different settings of various parameters (e.g. frequency, amplitude, offset, and
start phase) of the carrier waveform will affect the output FM modulated waveform.
For different carrier waveform shapes, the ranges of the various parameters are
different (the ranges are related to the instrument model that you are using and the
currently selected carrier waveform). For all carrier waveform shapes, the default
values are 1 kHz frequency, 5 Vpp amplitude, 0 Vdc offset, and 0° start phase.

When the carrier waveform currently selected is Sine, Square, or Ramp, please
refer to descriptions in "To Output Basic Waveform" to set the parameters of
the carrier waveform currently selected.

When the carrier waveform currently selected is arbitrary waveform, please
refer to descriptions in "To Output the Arbitrary Waveform" to set the
parameters of the carrier waveform currently selected.
