Generating a PM Modulated Waveform
After selecting the Mod → PM (Phase Modulation) operator button,
WaveStation shows the PM Operation menu and corresponding Display
and Detail dialogs.
Press adjacent Operation buttons and use the Digital Input Front Panel
Controls to make specific adjustment/selection parameter choices. For
more information on getting to this point, see Navigating Interfaces,
Adjusting Parameters, and Making Selections (on page 11).
Modulated waveforms consist of a carrier waveform and a modulated
waveform. For PM, the phase of the carrier waveform varies with the
instantaneous voltage level of the modulated waveform.
Mod/PM Operation menu selections and parameters include PM Freq,
Phase Dev, Type, Shape, and Source as follows:

PM Freq - This parameter sets the frequency at which the output
amplitude shifts between the carrier amplitude and 0. The internal
source frequency range is 2 MHz to 50 kHz.

Phase Dev - This parameter sets the maximum phase deviation. Values
range from 0° to 360°.

Type - Phase Modulation.

Shape - Choose the waveform shape type (used as a carrier waveform)
for modulation. Sine, Square, Triangle, UpRamp, DnRamp, Noise, or Arb
waveforms may be modulated, while Pulse, and DC cannot.

Source - Select Internal or External. If External is selected, use the
Trig/Gate/Fsk/Burst connector on the Back Panel.
