5 SCPI Programming Reference
CURRent Subsystem
Current commands program the output current of the instrument.
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]? [MIN|MAX]
[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent[:LEVel]:TRIGgered[:AMPLitude]? [MIN|MAX]
Sets the immediate or triggered current level when the output is operating in current priority 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. The
minimum value is the most negative value.
Parameter
-102% to 102% of rating, *RST 0
Sets the positive current to 2 A: CURR 2
[SOURce:]CURRent:BWIDth:LEVel 0, <value>|MIN|MAX
[SOURce:]CURRent:BWIDth:LEVel? [MIN|MAX]
Specifies the low-pass filter corner frequency applied to the programming setpoint signal with the
current bandwidth. The value is in Hertz. The default frequency is optimized for maximum up-
programming speed as well as the fastest transient response time. It can be reduced to compensate
for output overshoots.
Parameter
0, (bandwidth range - required)
10 to 100,000, *RST 5,000
With the current bandwidth at 0, sets the frequency 60 Hz: CURR:BWID:LEV 0, 60
[SOURce:]CURRent:LIMit[:POSitive][:IMMediate][:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent:LIMit[:POSitive][:IMMediate][:AMPLitude]? [MIN|MAX]
[SOURce:]CURRent:LIMit:NEGative[:IMMediate][:AMPLitude] <value>|MIN|MAX
[SOURce:]CURRent:LIMit:NEGative[:IMMediate][:AMPLitude]? [MIN|MAX]
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
Positive: 0 to 102% of rating, *RST 1.02% of rating
Negative: -102% of rating to 0, *RST -1.02% of rating
Sets the positive current limit to 2 A: CURR:LIM 2
Sets the negative current limit to -2 A: CURR:LIM:NEG -2
