FIGURE B-1. PROGRAMMING THE OUTPUT
B.12 OUTPut[:STATe] COMMAND
OUTP
Syntax: Short Form: OUTP[:STAT] Long Form: OUTPut[:STATe]
=(0 or OFF, 1 or ON)
Description: Enables or disables the power supply output. The factory default for power-up is Local mode, the
output is on and the front panel controls affect the unit's operation; however note that the factory
default for power-up can be changed from the front panel (see PAR. 3.3.7). Upon entering Remote
mode, the output. status is not affected.
For passive loads, when OUTP OFF is executed, the programmed values of voltage and current
are saved, then voltage and current are programmed as follows: when the unit is operating as a volt-
age source, voltage is programmed to zero and current protect is programmed to a low value; when
operating as a current source, current is programmed to zero and voltage protect is programmed to a
low value. When OUTP ON is executed, the power supply output is restored to the previously saved
programmed values. The saved values of voltage and current can be viewed by VOLT? and CURR?
queries.
For active loads (inductive, capacitive, battery or other electronic loads) programming the appro-
priate settings for mode, voltage and current is recommended instead of using the OUTP OFF com-
mand. Follow the guidelines presented in Table 3-6 to understand how the unit responds to OUTP
OFF.
instead of using OUTP OFF, program the unit to current mode using the FUNC:MODE command, then program
output current to zero.
Related Commands: FUNC:MODE, OUTP?.
NOTES: 1. The power supply is assumed to be operating in constant voltage mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.5.2 for pro-
gramming techniques to optimize performance.
OUTP ON Turns the output on.
VOLT 21; CURR 1.5 Power supply output programmed to go to 21V, current limit 1.5A
INIT:CONT ON Continuous triggers enabled.
INIT:CONT? Power supply returns “1.”
VOLT:TRIG 15;CURR:TRIG 3 Power supply output programmed to return to 15V, current limit
3A upon receipt of trigger.
*TRG Power supply output returns to 15V,current limit 3A.
VOLT 21; CURR 5E-2 Power supply output programmed to go to 21V, current limit 0.05A
MEAS:VOLT? If actual value of output voltage is 20.9V, power supply
returns 2.09E1 within the limits of readback accuracy.
MEAS:CURR? If actual value of output current is 0.0483A, power supply
returns 4.83E-2 within the limits of readback accuracy.
FUNC:MODE CURR Establishes constant current mode as power supply operating mode.
VOLT 21; CURR 1.1 Power supply programmed to voltage limit 21V, 1.1A.
CURR? Returns 1.1.
FUNC:MODE VOLT Establishes constant voltage mode as power supply operating mode.
CURR:TRIG? Returns 3 (current value established by CURR:TRIG).
VOLT:TRIG? Returns 15 (voltage value established by VOLT:TRIG).
*TRG Power supply output returns to 15V, current limit 3A.
INIT:CONT 0 Triggers disabled.
INIT:CONT? Power supply returns “0.”
VOLT 0 Power supply output programmed to go to 0V.
MEAS:VOLT? Returns 0 within the limits of readback accuracy (measured output
voltage).
VOLT? Returns 0 within the limits of readback accuracy (programmed output
voltage).
CURR? Returns 3 (programmed current).
MEAS:CURR? Returns 0 within the limits of readback accuracy (measured output
current).
