Signal Descriptions for SYSTEM BUS

PULSE_MOD_IN	Pin 6 Input
	This is the pulse modulation input. This signal is connected directly in parallel with
	the PULSE (MODULATION IN) front-panel connector.
NOTE	The two inputs are directly coupled to each other. Avoid putting signals on both
	inputs simultaneously.

RP_BURST_T1,	T1-Pin 26, T2-Pin 8 Select/Control
RP_BURST_T2	These are the rear-panel power ramp burst type select signals. They are connected to
	the DSP analyzer. These signals can be used during power ramp measurements to
	select the burst type in real-time for each burst being operated on.
	When digitally demodulating, burst select must be set to Ext to use these signals.
	When making triggered measurements, the measurement synchronization burst
	selection must be set to Ext. Each of the four burst type definitions can be selected.
