PSK (Phase Shift Keying)
Phase Shift Keying modulation is a modulation technique that shifts the output
signal phase between two phases: the carrier phase and modulating phase.
Carrier wave phase shifts to the modulating phase with the specified PSK rate,
and then returns to the original phase. The PSK user interface is shown
below.

How to set the parameters of PSK
(1) Press the Mode function key, press the NextPage softkey twice
more,then press the PSK softkey to enter PSK user interface.
(2) Select carrier wave shape:
The carrier wave can be Sine, Square, Ramp, or Arbitrary wave (except
DC). Press , , , or to select a desired carrier wave
shap.
(3) Set carrier wave parameters:
Press the wave shap key of the selected carrier wave to display the
waveform and parameters of the carrier wave. You can change the
parameters of the carrier wave. Press Mode to return to the modulation
mode interface.
(4) Select modulating wave source:
Press the Source softkey to select Internal or External as the modulating
wave source.
If you select Internal, the modulating wave is set as a Square with 50%
duty cycle. Press the PSK Rate softkey to set the PSK rate. The rate at
