Current Commands

Current commands program the output current and current protection functions. The SOURce
keyword is optional in the following commands.

[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude] <

value

>, (@<chanlist>)

[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]? [MIN|MAX,] (@<chanlist>)
[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude] <

value

>, (@<chanlist>)

[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude]? [MIN|MAX,] (@<chanlist>)

Sets the immediate current level and the triggered current level when the output is operating in
constant current mode. The triggered level is a stored value that is transferred to the output when an
output Step is triggered. Units are in amperes. The maximum value depends on the current rating of
the unit.

Parameter

Typical Return

0 - maximum|MIN|MAX, *RST 0
The maximum value is 102% of the current rating of
the power module.

<current level>

Sets the output current level to 3 A: CURR 3, (@1)
Sets the triggered current level to 2 A: CURR:TRIG 2, (@1)

l

The query returns the programmed current level in the form +n.nn for each channel spe-
cified. Multiple responses are separated by commas.

[SOURce:]CURRent:LIMit[:POSitive][:IMMediate][:AMPLitude] <

value

>, (@<chanlist>)

[SOURce:]CURRent:LIMit[:POSitive][:IMMediate][:AMPLitude]? [MIN|MAX,] (@<chanlist>)
[SOURce:]CURRent:LIMit:NEGative[:IMMediate][:AMPLitude] <

value

>, (@<chanlist>)

[SOURce:]CURRent:LIMit:NEGative[:IMMediate][:AMPLitude]? [MIN|MAX,] (@<chanlist>)

Sets the current limit when in voltage priority mode. Units are in amperes. The maximum value
depends on the current rating of the unit. The minimum value is the most negative value.

Parameter

Typical Return

Positive: 0 to 102% of rating|MIN|MAX, *RST 102%
Negative: -102% of rating to 0|MIN|MAX, *RST -102%

<+ current limit>
<- current limit>

Sets the positive current limit to 2 A: CURR:LIM 2 (@1)
Sets the negative current limit to -2 A: CURR:LIM:NEG -2 (@1)

l

MIN refers to the most negative value of the range. MAX refers to the least negative value of the
range.
