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 (on page 14).
Generating Sweep Waveforms
Specific waveform types may be swept (as carrier waveforms) using the
WaveStation.
Sine , Square , Ramp , or Arb waveforms may be swept,
while Pulse , Noise , and DC cannot. Frequency sweep mode uses the
WaveStation to sweep from the start frequency to the stop frequency at
a specified sweep rate.
The first step in creating a sweep waveform is to press the Sweep button
on the Front Panel (on page 13).
PLEASE NOTE THE FOLLOWING :

When using WaveStation (or any signal generator) it's important
to understand the relationship between the
Main Waveform Type
buttons, the Waveform Signal Conditioning function buttons, and
the Save/Recall , Utility , and Help function buttons. See Combined
Use of Waveform, Function, and Configuration Buttons (on page
23).

Default values for many controls can be set using certain options
available on the
Utility menu. Learn more in Main Utility
Operations (on page 62).
