:TRIGger<hw>:LFFSweep
Usage: Event
Manual operation: See "Execute Single Sweep" on page 223
Immediately starts an LF frequency sweep.
The command is effective in sweep mode "Single" (
LFO:SWE:MODE AUTO
in combina-
tion with
TRIG:LFFS:SOUR SING
).
:TRIGger<hw>:LFFSweep:SOURce <Source>
Sets the trigger source for the LF sweep. The trigger is triggered by the com-
mand

.
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 the 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>]:LFOutput:SWEep[:FREQuency]:
EXECute
or
*TRG
.
The mode has to be set to
AUTO
(
[:SOURce<hw>]:
LFOutput:SWEep[:FREQuency]:MODE
).
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

on.
