FIGURE B-3. PROGRAMMING THE OUTPUT

B.16 [SOURce:]CURRent:[:LEVel]TRIGgered[:AMPlitude] COMMAND

CURR:TRIG

Syntax:

Short Form: [SOUR:]CURR[:LEV]:TRIG[:AMP] <exp_value>
Long Form: [SOURce:]CURRent[:LEVel]:TRIGgered[:AMPlitude] <exp_value>
<exp_value> = 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: <exp_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.
