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 limit to 2 A: CURR:LIM 2
[SOURce:]CURRent:BWIDth:LEVel 0 | 1, <value>|MIN|MAX
[SOURce:]CURRent:BWIDth:LEVel? [MIN|MAX]
Specifies the low-pass filter corner frequency applied to the programming setpoint signal with the
indicated range of user-configurable setpoints. 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 | 1
10 to 5,000 all ranges
Sets the current bandwidth to 1, frequency 60 Hz: CURR:BWID:LEV 1, 60
[SOURce:]CURRent:BWIDth:RANGe 0 | 1
[SOURce:]CURRent:BWIDth[:RANGe]?
Sets the current compensation. This lets you optimize output response time with inductive loads.
These compensation modes only apply when the unit is operating in constant current (CC), both in
current priority and in voltage priority (when in current limit).
Parameter
0 Best suited for stability with a wide range of output inductances. Refer to
put Bandwidth
1 Provides maximum up-programming speed and the fastest transient response time
when the output inductance is restricted to small values.
