"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 either to the BNC connector EXT TRIG IN or to pin 2 of the USER
PORT connector at the rear panel. The two trigger inputs are equivalent; no addi-
tional setting for signal routing is required. For detailed specifications of the trigger
signals refer to
The "External" trigger mode can be configured using the
settings.
Note:
The period of the external trigger signal should be adjusted to the triggered
measurement sequence. If the analyzer receives a trigger event while the last
sequence is still running, the R&S
ZNB/ZNBT skips the trigger event and gener-
ates a message.
●
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.
Remote command:
Manual Trigger
Generates the trigger event for "Manual" trigger mode and is disabled unless this mode
is active.
Remote command:
*TRG
Sequence
Selects the measurement cycle or sequence of actions to be triggered.
●
"Sweep" means that each trigger event starts an entire sweep, according to the
current sweep configuration.
●
"Point" means that each trigger event starts the measurement at the next sweep
point.
●
"Partial Measurement" means that each trigger event starts the next partial mea-
surement at the current or at the next sweep point. If each measurement points
requires only one partial measurement, this option is equivalent to "Point".
