SINGle [BUS]
Executes one complete sweep cycle.
The following commands initiate a trigger event:
*TRG on page 355
[:SOURce<hw>]:SWEep:POWer:EXECute
[:SOURce<hw>]:SWEep[:FREQuency]:EXECute
:TRIGger<hw>[:SWEep][:IMMediate], :TRIGger<hw>:
PSWeep[:IMMediate] and :TRIGger<hw>:FSWeep[:
IMMediate].
Set the sweep mode with the commands:
[:SOURce<hw>]:SWEep:POWer:MODEAUTO|STEP
[:SOURce<hw>]:SWEep[:FREQuency]:MODEAUTO|STEP
[:SOURce<hw>]:LFOutput:SWEep[:FREQuency]:MODE
AUTO|STEP
In step mode (STEP), the instrument executes only one step.
EXTernal
An external signal triggers the sweep.
EAUTo
An external signal triggers the sweep. When one sweep is fin-
ished, the next sweep starts.
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: See Example"Setup an LF sweep" on page 461
Usage: Setting only
:TRIGger<hw>:FPSWeep:SOURce <FpTrigSource>
Selects the trigger source for the combined RF frequency / level sweep.
The parameter names correspond to the manual control. If needed, see table
Table 12-1 for selecting the trigger source with SCPI compliant parameter names.
Parameters:
<FpTrigSource> AUTO | IMMediate | SINGle | BUS | EXTernal | EAUTo
AUTO|IMMediate
Executes the combined RF sweep automatically. In this free-run-
ning mode, the trigger condition is met continuously. I.e. as soon
as a sweep is completed, the next one starts immediately.
SINGle|BUS
Executes one complete sweep cycle triggered by the GPIB com-
mands [:SOURce<hw>]:SWEep:COMBined:EXECute or
*TRG. The mode has to be set to [:SOURce<hw>]:SWEep:
COMBined:MODE > AUTO.
EXTernal
An external signal triggers the sweep.
