Pressing the front panel Pulse key reveals a menu of softkeys. These
softkeys are described in this section in alphabetical order.
Ext2 DC-Coupled
This softkey lets you input an external, DC-coupled, pulse modulation
signal to the EXT 2 INPUT connector.
The external 2 input has multiple uses but can be used for only one
modulation at a time. If, for example you were using the external 2
input in a frequency modulation configuration for
FM Path 1, and then
you configured the pulse modulation source to also use the external 2
input, the signal generator would turn off
FM Path 1 and assign the
external 2 input to your pulse configuration.

Fast Pulse Off On
This softkey enables fast pulse modulation from an external,
TTL-compatible pulse source via the PULSE IN BNC connector. Notice,
however, that although you can enable the fast pulse modulation state
with this softkey, the RF carrier is modulated by the pulse signal only
when you have also set
Mod On/Off to On. Whenever fast pulse
modulation is enabled, the
PULSE annunciator is turned on in the
display.
Default Value: Off
