:TRIGger<hw>:FSWeep[:IMMediate]
The command immediately starts an RF frequency sweep. The sweep to be executed
depends on the respective MODE setting (SOURce:SWEep:FREQuency:MODE SING).
The command corresponds to the manual-control "Execute Trigger".
SWE:FREQ:MODE SING
sets the Single trigger mode, i.e. a trigger starts a single sweep.
TRIG:FSW
starts a single RF frequency sweep.
Example:
EventUsage:
:TRIGger<hw>:FSWeep:SOURce <Source>
The command sets the trigger source for the RF frequency sweep.
The names of the parameters correspond directly to the various settings under manual
control. SCPI uses other names for the parameters; these names are also accepted by
the instrument. The SCPI names should be used if compatibility is an important consid-
eration.
An overview of the various names is given in table 7-3.
Parameters:
AUTO|IMMediate | SINGle|BUS| EXTernal
AUTO|IMMediate
The trigger is free-running, i.e. the trigger condition is fulfilled
continuously. As soon as one sweep is finished, the next sweep
is started.
SINGle|BUS
One complete sweep cycle is triggered by the IEC/IEEE-bus
commands SOURce:LFOutput:SWEep:FREQuency:EXEC or
*TRG. The mode has to be set to
AUTO (:SOURce:SWEep:FREQuency:MODE AUTO).
EXTernal
The sweep is triggered externally via the INST TRIG connector.
Path A = BNC connector; Path B = Pin at AUX I/O interface
SINGle
<Source>
*RST:
TRIG:FSW:SOUR EXT
selects triggering with an external trigger. The trigger is input via
the TRIGGER 1 connector.
Example:
:TRIGger<hw>:PSWeep[:IMMediate]
The command immediately starts an RF level sweep. The sweep to be executed depends
on the set sweep mode (:SOURce:SWEep:POWer:MODE). The command corresponds
to the manual-control command "Execute Trigger".
