Internal Pulse
This softkey lets you internally generate rectangular pulse modulation.
Configure the pulse modulation using the
Pulse Period and Pulse Width
softkeys. For additional specifications, refer to the technical
specifications document.
The internal source has multiple uses but can be used for only one
modulation at a time. If, for example you were using the internal source
in a frequency modulation configuration for
FM Path 1, and then you
configured the pulse modulation source to also use the internal source,
the signal generator would turn off
FM Path 1 and assign the internal
source to your pulse configuration.

Internal Square
This softkey lets you internally generate squarewave pulse modulation.
The duty cycle is set at 50% and you can set the pulse rate from 0.1 Hz
to 50 kHz. For additional specifications, refer to the technical
specifications document.
The internal source has multiple uses but can be used for only one

Pulse Off On
This softkey enables the pulse modulation for whichever pulse source
you have selected. Notice, however, that although you can enable the
pulse modulation state with this softkey, the RF carrier is modulated by
the enabled modulation only when you have also set
Mod On/Off to On.
Whenever pulse modulation is enabled, the
PULSE annunciator is
turned on in the display.
Default Value: Off
