4.16 Source Subsystem - Current
This subsystem programs the output current of the AC source.
Subsystem Syntax
[SOURce:]
CURRent
[:LEVel]
[:IMMediate]
[:AMPLitude] Sets the rms current limit
:PROTection
:DELay Current limit fault delay
:STATe Enable/Disable rms current limit protection
CURRent
Phase Selectable
This command sets the rms current limit of the specified output phase. If the output current
exceeds this limit, the output voltage amplitude is reduced until the rms current is within the limit.
The CL bit of the questionable status register indicates that the current limit control loop is active.
If the current protection state is programmed on, the output latches into a disabled state when
current limiting occurs.
Note that the CURRent command is coupled with the VOLTage:RANGe.This means that the
maximum current limit that can be programmed at a given time depends on the voltage range
setting in which the unit is presently operating. Refer to Section 6.3 under "Coupled Commands"
for more information. To determine the maximum available current, use the “curr? max” query
Command Syntax [SOURce:]CURRent[:LEVel]
[:IMMediate][:AMPLitude]
Parameters 0 to max. available current
Unit: A (rms amperes)
*RST 1
Examples CURR 5.0 CURR:LEV .5.0
Query Syntax [SOURce:]CURRent[:LEVel]
[:IMMediate][:AMPLitude]?
Returned Parameters
Related Commands CURR:PROT:STAT VOLT:RANG
CURRent:PROTection:DELay
This command holds off the over current trip of the output voltage for the time specified. Default
value at *RST is 0.1 sec. The range is from 0.1 to 5.000 secs and can be queried with the
CURR:PROT:DEL? MIN and CURR:PROT:DEL? MAX commands.
Command Syntax [SOURce:]CURRent:PROTection:DELay
Parameters 0.100 to 5.000 | MINimum | MAXimum
Unit: S (seconds)
*RST Value 0.100
Examples CURR:PROT:DEL 1.5
Query Syntax [SOURce:]CURRent:PROTection:DELay?
CURRent:PROTection:DELay? Min
CURRent:PROTection:DELay? Max
