Measurement Sync
17. Sync Pattern
Start Position
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.

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.
