Step Remote Operation
 Step Programming Functions
STEP
This subsystem programs the stepping functions for stepping mode. The number of loops, step values, and dwell t imes
are programmed for a specified operating mode.
[SOURce:]STEP:COUNt
This command sets the number of times that the STEP is executed before it is completed. The command accepts
parameters in the range 1 through 65535, or infinity (0). Program "0 (infinity)" as the command parameter will execute a
STEP indefinitely.

[SOURce:]STEP:CURRent:TIMe?
This command specifies the dwell time for each STEP. Each value of point represents the time in milli-seconds that the
input will remain at the particular STEP point before completing the step. At the end of the dwell t ime, the input of the
electronic load depends upon the following conditions:
■ If STEP:CURRent:STATe ON has been programmed, the input automatically changes to the next
point in the STEP.
■ If STEP:CURRent:STATe AUTO has been programmed, the input waits for a trigger command to
change to the next point in the STEP.
■ If STEP:CURRent:STATe ONCE has been programmed, the input remains at the present level until
a trigger sequences the next point in the STEP.

[SOURce:]STEP:CURRent:STATe
This command specifies how to process the STEP sequencing. The following parameters may be specified.
■
ON Causes the entire STEP to be executed immediately, paced by its dwell delays. As each dwell
delay elapses, the next point is immediately executed.
