softkey to select the modulating wave.
(5) Set modulating wave frequency
Press Frequency softkey to set the modulating wave frequency. The
range is 2 mHz – 100 kHz.
(6) Set frequency deviation
Frequency deviation is the deviation of the modulating wave frequency
relative to the carrier wave frequency. Press the Deviation softkey to set
the FM frequency deviation. Frequency deviation range: 1 uHz ≤ deviation
< min (min is carrier frequency or carrier maximum frequency minus
carrier frequency, the smaller of the two).
PM (Phase Modulation)
The modulated waveform consists of the carrier wave and the modulating
wave. For PM, the phase of the carrier wave varies with the instantaneous
voltage of the modulating wave. The PM user interface is shown below.

How to set the parameters of PM
(1) Press the Mode function key, press the NextPage softkey, then press the
PM softkey to enter PM user interface.
(2) Select carrier wave shape
The carrier wave can be Sine, Square, Ramp, or Arbitrary wave (except
