17.Sync Pattern Start Position

Screens

Measurement Sync

This field is only displayed when Burst Type is set to User Def. It selects the starting bit position of a user defined synchronization pattern.

Range 0 to 147.

18.Sync Status This field displays problems that were detected during digital demodulation or DSP analyzer measurements.

	See Also	Making Measurements: Solving Problems Messages
19. Trig Delay	This field sets the time delay between a valid trigger event and the beginning of a
	measurement.
	Range	0 to 5000.00 μs.
20. Trig Qual	This field selects whether a trigger qualifier will be used.
	Choices	Normal, no trigger qualifier is used.
		RF Power, trigger events will only be valid when RF power is
		detected at the selected input. If no RF Power is present at the time
		of the trigger, the measurement will re-arm after seven timeslots.
NOTE	If no measurements are being made while in continuous (Cont), check Trig Qual (see
	Screens:RF Generator/RF Analyzer). If it is set to RF Power, change it to Normal.

21.Trig Source This field selects the source of the trigger. When Activated (see Screens: Cell Configuration), triggers for digital demodulation are generated internally.

Choices	Ext Demod selects triggering through RP_DMOD_TRIG on the
	rear-panel SYSTEM BUS CONNECTOR.
	RF Rise selects triggering when the rising edge of an RF signal is
	detected. RF Rise is used with pulsed RF input signals.
	Ext Meas selects triggering through the MEASURE TRIGGER IN
	front panel connector.
