ESG Family Signal Generators Programming Commands and Examples
:LIST Subsystem
List Direction
:LIST:DIRection UP|DOWN
:LIST:DIRection?
This command sets the direction of execution of a list sweep. The choices are Up or Down.
Choose
UP to sweep from the first point in the list to the last point, or from the step sweep
start frequency and amplitude to the stop frequency and amplitude. Choose
DOWN to reverse
the direction of the sweep.
*RST Value: Up
List Mode
:LIST:MODE AUTO|MANual
:LIST:MODE?
This command sets the operating mode of a list sweep. The choices are Auto or Manual.
When in manual mode, the selected point controls the frequency and amplitude according
to the sweep type.
*RST Value: Auto
List Trigger Source
:LIST:TRIGger:SOURce BUS|IMMediate|EXTernal|KEY
:LIST:TRIGger:SOURce?
This command sets the point-to-point triggering source for the sweep. The choices are Bus
(trigger a list or step sweep using the GPIB), Immediate (immediately triggers the current
sweep), External (trigger a list or step sweep on a signal applied to the TRIGGER IN rear
panel connector), or Key (triggers the step when you press the
Trigger front panel key). The
sweep must be initiated (and the sweep trigger received) before the point-to-point trigger
can cause the sweep to go to the next point.
*RST Value: Immediate
List Type
:LIST:TYPE LIST|STEP
:LIST:TYPE?
This command sets the type of sweep. The choices are List and Step. You create a list
sweep by supplying the frequency, amplitude, and dwell time for each point in the sweep.
You create a step sweep by supplying the start and stop frequency and amplitude, the
number of points, and a dwell time. The signal generator then determines the values of
each point between the first and last point in a linear manner.
*RST Value: List
