Current Subsystem

This subsystem programs the output current of the power supply.

CURR

CURR:TRIG

These commands set the immediate current level or the pending triggered current level of the power supply. The immediate level is the current programmed for the output terminals. The pending triggered level is a stored current value that is transferred to the output terminals when a trigger occurs. A pending triggered level is unaffected by subsequent CURR commands and remains in effect until the trigger subsystem receives a trigger or an ABORt command is given. If there is no pending CURR:TRIG level, then the query form returns the CURR level. In order for CURR:TRIG to be executed, the trigger subsystem must be initiated (see INITiate).

[SOURce]:CURRent[LEVel]:TRIGgered [:AMPLitude]? MAX

 

[SOURce]:CURRent[:LEVel]:TRIGgered [:AMPLitude]? MIN

Returned Parameters

<NR3> CURR? and CURR:TRIG? return presently programmed immediate and

 

triggered levels. If not triggered level is programmed, both returned values are the same.

 

CURR? MAX and CURR? MIN return the maximum and minimum programmable

 

immediate current levels.

 

 

CURR:TRIG? MAX and CURR:TRIG? MIN return the maximum and minimum

 

programmable triggered current levels.

CURR *RST

CURR:PROT:STAT

This command enables or disables the power supply overcurrent protection (OCP) function. If the overcurrent protection function is enabled and the power supply goes into constant-current operation, then the output is disabled and the Questionable Condition status register OC bit is set (see "Chapter 4 - Status Reporting"). An overcurrent condition can be cleared with the OUTP:PROT:CLE command after the cause of the condition is removed.
