FIGURE B-3. PROGRAMMING THE OUTPUT
B.16 [SOURce:]CURRent:[:LEVel]TRIGgered[:AMPlitude] COMMAND
CURR:TRIG
Syntax: Short Form: [SOUR:]CURR[:LEV]:TRIG[:AMP]
Long Form: [SOURce:]CURRent[:LEVel]:TRIGgered[:AMPlitude]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Programs current value to be transferred to output by *TRG commands. Actual output current
will depend on load conditions. If the value exceeds the maximum for the model being programmed,
error message -222,”Data out of range” is posted in output queue. Related Commands: CURR. (See
example, Figure B-3.)
B.17 [SOURce:]CURRent:[:LEVel]TRIGgered[:AMPlitude]? QUERY
CURR:TRIG?
Syntax: Short Form: [SOUR:]CURR[:LEV]:TRIG[:AMP]?
Long Form: [SOURce:]CURRent[:LEVel]:TRIGgered[:AMPlitude]?
Return Value: = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Returns the current value established by CURR:TRIG command. (See example, Figure B-3.)
NOTES: 1. The power supply is assumed to be operating in constant voltage (CV) mode.
2 Examples below are intended only to illustrate command functions. Refer to PAR. 3.5.4 for pro-
gramming techniques to optimize performance.
OUTP ON Output enabled.
OUTP? Power supply returns “1” (output enabled).
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 2.09E+1.
MEAS:CURR? If actual value of output current is 0.0483A, power supply
returns 4.83E-2.
FUNC:MODE? Returns VOLT if power supply operating in constant voltage
mode, CURR for constant current 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 21V, current limit 0.05A.
INIT:CONT 0 Triggers disabled.
INIT:CONT? Power supply returns “0.”
OUTP OFF Output disabled.
OUTP? Returns 0 (output disabled).
MEAS:VOLT? Returns 0. (measured output voltage).
VOLT? Returns 17.(programmed output voltage)/
CURR? Returns 1.5 (programmed current)
CURR? MAX Returns 4 (assuming maximum allowable current for power
supply being addressed is 4A, i.e. ABC 25-4DM).
CURR? MIN Returns 0 (minimum allowable current).
CURR? Returns 1.5, indicating programmed current value = 1.5A.
SYST:VERS? Returns 1997.0.
