The command is effective in sweep mode "Single" (
LFO:SWE:MODE AUTO
in combina-
tion with
TRIG:LFFS:SOUR SING
).
Usage: Event
Manual operation: See "Execute Single Sweep" on page 223
:TRIGger<hw>:PSWeep:SOURce <Source>
Sets the trigger source for the RF level 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 7-2 .
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:POWer:EXECute
,
:TRIGger<hw>:
PSWeep[:IMMediate]
or
*TRG

AUTO
(
:SOURce:SWEep:LEVel:MODE AUTO
).
EXTernal
The sweep is triggered externally via the INST TRIG connector.
EAUTo

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.
