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 EXT TRIG IN
– Pin 2 of the USER PORT connector
– Pin 18 of the Handler I/O (Universal Interface)
The trigger inputs are equivalent; no additional setting for signal routing is required.
For detailed specifications of the trigger signals, refer to Chapter 11.3.1.1, "USER
PORT", on page 1381.
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 different external trigger sources.
