The following buttons in the "Trigger" tab open related dialogs:
●
"Trigger Manager...": Trigger Manager dialog
●
"Trigger Out Manager...": Trigger Out 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 connectors Trigger In A to D
(requires trigger board R&S ZNA-B91)
– Pin 2 of the User Port connector
See "Source" on page 562. For detailed specifications of the trigger signals, refer
to Chapter 12.3.1.1, "User Port", on page 1779.
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.
