3.9.1 Selecting PM Modulation
The 81150A / 81160A will allow only one modulation mode to be enabled at
a time. For example, you cannot enable PM and AM at the same time. When
you enable PM, the previous modulation mode is turned off.
The 81150A / 81160A will not allow PM to be enabled at the same time that
sweep or burst is enabled. When you enable PM, the sweep or burst mode
is turned off.
You must enable PM before setting up any of the other modulation
parameters. Press and then select “PM” using the Modulation Type
softkey. The PM waveform is output using the present settings for the
carrier frequency, modulating frequency, output amplitude, and offset
voltage.

Operation
To avoid multiple waveform changes, enable PM after you have set up the
other modulation parameters.
