Trigger
The Trigger submenu selects the source of the trigger signal and provides additional Trigger Settings .
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 ). Triggered measurements are an
alternative to the default mode (Free Run, Continuous Sweep) , where the measurement is continuously
repeated without fixed time reference.
Any trigger event may 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.
The trigger settings are ignored for calibration sweeps (see Measure Standards dialog). Each
calibration sweep is started without delay (Free Run measurement).
•
Free Run is the default trigger mode. A new measurement is started immediately without
waiting for a trigger signal and without fixed time reference.
•
The External trigger signal is applied to the EXT TRIGGER or USER CONTROL connector at
the rear panel.
•
The Periodic trigger signal is provided by an internal clock generator.
•
In Manual trigger mode, the trigger signal is generated on pressing the Manual Trigger softkey.
•
Trigger Settings opens a dialog to specify the operation that the analyzer carries out after
receiving a trigger event.
