Turn the 2470 output on or off
You can turn the 2470 output on from the front panel or by sending remote commands.
Turning the 2470 output off does not place the instrument in a safe state (an interlock is
provided for this function).
Hazardous voltages may be present on all output and guard terminals. To prevent electrical
shock that could cause injury or death, never make or break connections to the 2470 while
the instrument is powered on. Turn off the equipment from the front panel or disconnect the
main power cord from the rear of the 2470 before handling cables. Putting the equipment into
an output-off state does not guarantee that the outputs are powered off if a hardware or
software fault occurs.
When the source of the instrument is turned off, it may not completely isolate the instrument from the
external circuit. You can use the Output Off setting to place the 2470 in a known, noninteractive state
during idle periods, such as when you are changing the device under test. The output-off states that
can be selected for a 2470 are normal, high-impedance, zero, or guard.
See "Output-off state" in the 2470 Reference Manual for additional details.
Using the front panel:
Press the OUTPUT ON/OFF switch. The instrument is in the output-on state when the switch is
illuminated. The instrument is in the output-off state when the switch is not illuminated.
Using SCPI commands:
To turn the output on, send the command:
:OUTPut:STATe ON
To turn the output off, send the command:
:OUTPut:STATe OFF
Using TSP commands:
To turn the output on, send the command:
smu.source.output = smu.ON
To turn the output off, send the command:
smu.source.output = smu.OFF
