Signal Descriptions for SYSTEM BUS

RP_TXD, RP_RXD	TXD-Pin 37 RXD-Pin 18 Output/Input
	These are the rear-panel serial transmit data and rear-panel serial receive data lines.
NOTE	Ground signals not listed individually here.
RP_TX_HOP	Pin 28 Input
	This is the rear-panel trigger signal input for hopping the RF generator (if selected).
	It is used when externally addressing the hop frequencies. It is connected to the hop
	controller. It can also be configured to control RF generator output pulsing
	(automatic level pulsing when this trigger occurs).
	You must supply signals on the rear-panel hop frequency table address input lines to
	select each RF generator hop frequency for each hop trigger. Also, the hop
	controller’s hop address Source field must be set to Ext.
	This line is active when the hop controller’s Source field is set to Ext, the RF
	generator’s hop mode is set to Hop, and the RF generator’s hop trigger is set to Arm.
	Requirements	Amplitude: TTL levels High drive requirement: 100 μA Low

SEQ_TRIG_OUT	Pin 9 Output
	This is the sequence trigger output. It is connected to the DSP analyzer. It outputs a
	positive-going pulse when an internal sequence goes through something other than
	the next higher address, or when reset occurs (Hop Address Source=Int).
