:TRIGger<hw>:FSWeep:SOURce <Source>
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:
<Source> AUTO | IMMediate | SINGle | BUS | EXTernal | EAUTo
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 GPIB commands
[:SOURce<hw>]:SWEep[:FREQuency]:EXECute
,
:
TRIGger<hw>:FSWeep[:IMMediate]
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.
EAUTo
The sweep is triggered externally via the INST TRIG connector.
As soon as one sweep is finished, the next sweep is started. A
second trigger event stops the sweep at the current frequency, a
third trigger event starts the trigger at the start frequency, and so
on.
*RST:
AUTO
Example:
TRIG:FSW:SOUR EXT
selects triggering with an external trigger.
Manual operation: See "Mode - RF Frequency Sweep" on page 262
