: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 7-2 .
Parameters:
