TRIGger:SYNC:STATe <state>
Available in:
●
Continuous average mode with TRIGger:SOURce IMMediate
●
Trace, timeslot modes with TRIGger:SOURce INTernal
Enable the synchronization state if you want to synchronize several power sensors
connected to a base unit. The synchronization works as follows.
The external trigger bus is blocked as long as a power sensor is in the "measuring"
state. The external trigger bus is enabled only when all power sensors are in the "wait-
ing for trigger" or "idle" state. Thus, the power sensors start to measure simultaneously.
Make sure that the measurement time is the same for all power sensors involved in the
measurement. Otherwise, the trigger bus is blocked by any power sensor that has
completed its measurement before the others and has returned to the "idle" state.

= measurement time
During the measurement, the trigger synchronization is high. For a continuous average
measurement, the measurement time is calculated as described in Chapter 8.6.1.4,
"Calculating the measurement time", on page 57.
For a trace or timeslot measurement, one measurement cycle is one sweep.
For details on trigger states, see Chapter 8.5.2.1, "Trigger states", on page 43.
Parameters:
<state> *RST: OFF
8.6 Configuring the measurement modes
In the following, the settings needed for configuring a measurement mode are descri-
bed.

8.6.1 Continuous average measurement
The continuous average mode measures the signal average power asynchronously
within definable time intervals (sampling windows). The aperture (width of the sampling
windows) can be defined.
