[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 value representing voltage value to be programmed by *TRG command established by
CURR:TRIG command).

(See example, Figure B-1.)

[SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude] COMMAND



VOLT

Syntax:

Short Form: [SOUR:]VOLT[:LEV][:IMM][:AMP] <exp_value>
Long Form: [SOURce:]VOLTage[:LEVel][:IMMediate][:AMPlitude] <exp_value>
<exp_value> = 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
VOLT:LIM[:HIGH] value, error message -222,”Data out of range” is posted in output queue. Related
Commands: *RCL, *SAV, VOLT:LIM[:HIGH]. (See example, Figure B-1.

[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 minimum 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.,
500V for BHK 500-80MG). VOLT? MIN returns minimum voltage allowed for power supply (always 0).
Related Commands: VOLT. (See example, Figure B-5.)

B.52

[SOURce:]VOLTage:LIMit[:HIGH] COMMAND



VOLT:LIM[:HIGH]

Syntax:

Short Form: [SOUR:]VOLT:LIM[:HIGH] <exp_value>
Long Form: [SOURce:]VOLTage:LIMit[:HIGH] <exp_value>
<exp_value> = digits with decimal point and Exponent, e.g., 2.71E+1 for 27.1

Description:

Sets voltage limit for power supply output.

If the value exceeds the voltage protection value (set by

VOLT:PROT, see PAR. B.56), error message -222,”Data out of range” is posted in the output queue.
NOTE: If the voltage limit is changed, any previously established trigger levels higher than the new
limit must be reprogrammed to be lower than the new limit; otherwise triggers will cause the output to
exceed the new limit. Once the limit is established, the unit will not accept trigger values higher than
the programmed limit. Related Commands: VOLT. (See example, Figure B-5. See PAR. 3.3.6.2 and
Figure 3-2 for special programming considerations.

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. 3.3.6 for

programming techniques to optimize performance.

OUTP ON

Output enabled.

VOLT 421;CURR 1.1E-2

Power supply programmed to voltage limit 421V, 0.011A.

CURR?

Returns 1.1E-2.

CURR:LIM[:HIGH] 3.3E-2

Current limit set to 0.033A.
