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.
