Signal Descriptions for SYSTEM BUS

DATA-Pin 22 CLK-Pin 4 VALID-Pin 23 Outputs

These are the digital demodulation data output signal, the digital demodulation clock output signal, and the digital demodulation valid output signal. These signals are connected directly in parallel with their respective front-panel connectors.

See Also	Front Panel Connectors: DATA (DEMODULATION OUT),
	CLOCK (DEMODULATION OUT), VALID
	(DEMODULATION OUT)

FP_DATA,	DATA-Pin 1 CLOCK-Pin 20 Inputs
FP_CLOCK	These are the front-panel DATA, and CLOCK inputs. These signals are connected

	directly in parallel with their respective front-panel connectors.

NOTE	The two inputs are directly coupled to each other. Avoid putting signals on both
	inputs simultaneously.
	See Also	DATA (MODULATION IN) CLOCK (MODULATION IN)

G_EXT_TRIG_	Pin 24 Output
OUT	This output is a 1-bit-wide trigger. The timeslot and bit position in the timeslot are

	programmable on the Service screen.
	Requirements	Amplitude: TTL Levels Low Drive: 10 μA High Drive: 2 mA
	See Also	Screens: Service
MEAS_TRIG_OUT	Pin 21 Output
	This output signals when a DSP measurement is being made. It is used as an
	auxiliary trigger output signal for use with an external spectrum analyzer.
