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.
Background information
Refer to Chapter 4.1.4.1, "Partial measurements and driving mode", on page 111.
Output trigger
If the R&S ZNA is equipped with the Trigger Board option R&S ZNA-K91, it provides
four configurable output trigger signals that can be used to synchronize external devi-
ces with the measurement. These signals are available at the rear panel connectors
Trigger Out A to D.
5.10.4.1 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.
