9.5.3.1 Controls on the Trigger Tab
The following buttons in the "Trigger" tab open related dialogs:
●
"Trigger Manager...": Trigger Manager Dialog
FreeRun / External / Manual / Multiple Triggers
These four buttons select the trigger source:
●
In "FreeRun" mode, a new measurement is started immediately without waiting for
a trigger event and without fixed time reference. The remaining trigger settings are
not valid.
"FreeRun" means that a measurement in "Continuous" sweep mode is repeated as
fast as possible.
●
In "External" trigger mode, the measurement is triggered by an external 5 V TTL
signal, applied to one of the following rear panel connectors:
–
BNC connector Trigger In
– Pin 2 of the Aux. Port connector
(R&S
ZNL only, requires Additional Interfaces option R&S FPL1-B5)
The trigger inputs are equivalent; no additional setting for signal routing is required.
For detailed specifications of the trigger signals, refer to
Chapter 12.3.1.1, "Aux.
Port" , on page 972.
The "External" trigger mode can be configured using the Sequence , Delay and Sig-
nal Type settings.
●
In "Manual" trigger mode, the trigger signal is generated by the "Manual Trigger"
button.
●
If "Multiple Triggers" is active, the trigger sources for different triggered measure-
ment sequences, the trigger slope, and the trigger delay can be selected individu-
ally using the
Trigger Manager Dialog .
In particular, it is possible to use two different external trigger sources (R&S ZNL
only).
