TRIG
starts all active sweeps.
Example:
EventUsage:
:TRIGger<hw>[:SWEep]:SOURce <Source>
The command sets the trigger source for all sweeps.
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 7-3.
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:LFOutput: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:
TRIG0:SOUR EXT
selects triggering with an external trigger. The trigger is input via
the INST TRIG connector.
Example:
Setting onlyUsage:
7.20 UNIT Subsystem
The UNIT subsystem contains the commands specifying which units are valid if no unit
is indicated in a command. These settings are valid for the entire instrument.
:
UNIT:ANGLe <Angle>
The command defines the default unit for the phase modulation angle. It is not valid for
other commands which determine angle values, e.g. RF phase. It does not influence the
manual control parameter unit and the display.
