This 

 activates the pulse modulation mode for an external

pulse source. The pulse source is connected to the PULSE INPUT

BNC connector and fed to the pulse modulator through a buffer
circuit.

When pulse modulation is in effect, the RF output is turned on
(programmed power is produced) and off 

 

 attenuation) at a

rate determined by the pulse modulation input. Pulse and amplitude
modulation can be in effect simultaneously. An asterisk next to the
key label indicates that this feature is active.

This 

 activates pulse modulation mode using the internal pulse

generator. No external connection is needed. When internal pulse
modulation is selected the PULSE INPUT BNC becomes an output
for the internally generated signal. An asterisk next to the 
label indicates that this feature is active. The pulse parameters
(width, period, rate, rise time, etc.) are controlled by softkeys. See

Pulse Menu (or 

Menu for synthesizers with Option 002)

for a list of these softkeys.
