Command Groups
Measurement Commands
Measurement commands are used to query parameters. The
MEASure
commands
initiate and execute a complete measurement cycle and are recommended for
measuring voltage and current at the outputs of the power supply.
FETCh
commands do not initiate a new measurement cycle but rely on measurements
stored in the communication buffers of the power supply. The
FETCh
commands
are provided for voltage and current measurements to maintain compatibility
with other instruments. Output power, however, is only available using a
FETCh
command.
Table 2-11: Measurement commands
Command Description
MEASure[:SCALar][:VOLTage][:DC]? Initiate a measurement and query the measured output voltage
MEASure[:SCALar]:POWer[:DC]?
Initiate a measurement and query the measured output current
MEASure[:SCALar]:CURRent[:DC]?
Initiate a measurement and query the measured output current
FETCh[:SCALar]:CURRent[:DC]? Query the output current stored in the communications buffer
FETCh[:SCALar]:POWer[:DC]? Query the output power stored in the communications buffer
FETCh[:SCALar]:VOLTage[:DC]? Query the output voltage stored in the communications buffer
Source Commands
These commands allow you to set various output parameters. Some of the
commands are used to con
fi gure protection functions like output timers and Max
Voltage.

[SOURce:]CURRent[:LEVel]:DOWN[:IMMediate][:AMPLitude] Set the current level to decrease a step.
[SOURce:]CURRent[:LEVel][:IMMediate]:STEP[:INCRement] Set or query the current step value.
[SOURce:]OUTPut:TIMer[:STATe] Set or query the state of the output timer.
[SOURce:]OUTPut[:STATe][:ALL] Set or query power supply output on or off.
[SOURce:]OUTPut:TIMer:DELay Set or query the time duration of output timer.
[SOURce:]VOLTage[:LEVel][IMMediate][:AMPLitude] Set or query voltage level.
[SOURce:]VOLTage[:LEVel]:UP[:IMMediate][:AMPLitude] Set to increase the voltage level by a step.
[SOURce:]VOLTage[:LEVel]:DOWN[:IMMediate][:AMPLitude] Set to decrease the voltage level by a step.
[SOURce:]VOLTage[:LEVel][:IMMediate]:STEP[:INCRement] Set or query the voltage step value.
[SOURce:]VOLTage:LIMit:STATe Set or query enable/disable voltage limit function.
[SOURce:]VOLTage:LIMit[:LEVel] Set or query the maximum output voltage setting.
