FIGURE C-4. PROGRAMMING CURRENT
C.18 [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude] COMMAND
VOLT
Syntax: Short Form: [SOUR:]VOLT[:LEV][:IMM][:AMP]
Long Form: [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Sets programmed voltage level at power supply output. This command programs output voltage
to a specific value; actual output voltage will depend on load conditions. If the value exceeds the max-
imum for the model being programmed, error message -222,”Data out of range” is posted in output
queue. (See example, Figure C-3.
C.19 [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude]? QUERY
VOLT?
Syntax: Short Form: [SOUR:]VOLT[:LEV][:IMM][:AMP]? {MIN | MAX}
Long Form: [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude]? {MIN | MAX}
Description: Identifies programmed voltage, maximum allowable voltage, or miniimum voltage (always 0).
The VOLT? query returns the programmed value of voltage. Actual output voltage will depend on load
conditions. The VOLT?MAX query returns the maximum voltage allowed for a particular model (e.g.,
25V for Kepco’s MST25-8DM). VOLT? MINReturns minimum voltage allowed for power supply
(always 0). Related Commands: VOLT. (See example, Figure C-3
C.20 [SOURce:]VOLTage:[:LEVel]TRIGgered[:AMPlitude] COMMAND
VOLT:TRIG
Syntax: Short Form: [SOUR:]VOLT[:LEV]:TRIG[:AMP]
Long Form: [SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPlitude]
= digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Programs voltage value to be transferred to output by *TRG commands. Actual output voltage
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. (See example, Figure C-3.)
C.21 [SOURce:]VOLTage:[:LEVel]TRIGgered[:AMPlitude]? QUERY
VOLT:TRIG?
Syntax: Short Form: [SOUR:]VOLT[:LEV]:TRIG[:AMP]?
Long Form: [SOURce:]VOLTage[:LEVel]:TRIGgered[:AMPlitude]?
Return Value: = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1
Description: Returns value representing voltage value to be programmed by *TRG command established by
VOLT:TRIG command). (See example, Figure C-3.)
NOTE: The power supply is assumed to be operating in constant voltage (cV) mode.
VOLT 21; CURR 1.1 Power supply programmed to voltage limit 21V, 1.1A.
CURR? Returns 1.1.
CURR 4.2 Power supply output current programmed to 3.3A, error message
-301 posted.
CURR? Returns 3.3.
--- OVERCURRENT CONDITION (1 SECOND) OCCURS.
CURR? Returns small value (approx. 1% of full scale current rating).
CURR 2.5 Power supply output current programmed to 2.5A
--- OVERCURRENT CONDITION (1 SECOND) OCCURS.
(After 10 seconds)
CURR? Returns 2.5.
