Trigger system of the analyzer
The trigger system is used to synchronize the analyzer's actions with events that can
be provided by an internal or external signal or user-generated ("Manual Trigger"). Trig-
gered measurements are an alternative to the default mode ("FreeRun", "Continuous"
sweep), where the measurement is continuously repeated without fixed time reference.
Any trigger event can start an entire sweep or a part of it. Moreover, it is possible to
switch off the RF source between consecutive triggered measurement sequences, and
to define a delay between trigger events and the measurement sequences.

Output trigger
The R&S ZNB/ZNBT provides a configurable output trigger signal to synchronize exter-
nal devices with the measurement. This signal is available at the rear panel connector
Trigger Out. Configuration of the output trigger signal is a remote control feature
(TRIGger:CHANnel<Ch>:AUXiliary... commands; see

5.10.3.1 Controls on the Trigger tab
The trigger settings are also valid for calibration sweeps. Hence, in external trigger
mode, the external trigger signal must be available during the system error correction,
too. To start the calibration sweeps without delay, use the "FreeRun" trigger type.
