to set the parameter. Use the numeric keyboard or direction keys and knob to
input the desired frequency value.
5.7 2PSK
You can configure the instrument to "shift" its output phase between two preset values using
2PSK modulation. The rate at which the output shifts between the two phases (called the "carrier
phase" and the "modulation phase") is determined by the internal signal level of the instrument or
the signal level on the front-panel
[Sync/Mod/Trig]
connector.
5.7.1 Select 2PSK Modulation
Press
Mod->Type->2PSK
to enable this function.
When
Mod
is enabled,
Sweep
or
Burst
will be disabled automatically.
After 2PSK is enabled, the instrument will generate 2PSK waveform with the currently specified
carrier and modulating waveforms. To avoid multiple waveform changes, enable modulation
after configuring the other modulation parameters.
5.7.2 Carrier Waveform Shape
2PSK carrier shape: Sine (default), Square, Ramp, Pulse, Arbitrary (except DC) or Harmonic
waveform.
Press the front panel key

,
Arb -> Type
or
Harmonic
to select a
desired carrier waveform shape.
Noise and DC could not be used as carrier waveform.
5.7.3 Carrier Phase
Choose carrier waveform shape, press
Phase
to highlight "Phase", and then use the numeric
keyboard or direction keys and knob to input the desired phase. The available phase ranges from
0º to 360º and the default value is 0º.
