17-64 SCPI Command Reference

SOURce subsystem

This subsystem is used to configure and control the I-Source and V-Source, and to set the
logic level (high or low) of each digital output line. The commands for this subsystem are sum-
marized in Table 17-6.
SOURce[1]
Use the following commands to configure and control the I-Source and V-Source. At the end
of this subsystem are program examples of sweeps and lists.
Control source output-off

Description
WARNING
This command is used to turn off the source output. The output will turn off
after all programmed source-measure operations are completed and the
instrument returns to the idle state.
Note that if auto output-off is enabled, the source output will automatically
turn off. See the next command.
<b> = 1 or ON
0 or OFF
:AUTO?
This command is used to control auto output-off for the source. With auto
output-off enabled, an :INITiate (or :READ? or MEASure?) will start
source-measure operation. The output will turn on at the beginning of each
SDM (source-delay-measure) cycle and turn off after each measurement is
completed.
With auto output-off disabled, the source output must be on before an
:INITiate or :READ? can be used to start source-measure operation. The
:MEASure? command will automatically turn on the source output. Once
operation is started, the source output will stay on even after the instrument
returns to the idle state. Auto output-off is the *RST and :SYSTem:PRESet
default.
With auto output-off disabled, the source output will remain on after all
programmed source-measure operations are completed. Beware of hazard-
ous voltage that may be present on the output terminals.
