Source and measure using SCPI commands
The SCPI commands that set up the source functions are in the SOURce subsystem.
The source commands are specific to each source function (voltage or current). For example, to set
the range to 100 mA for the current function, you would send:
:SOURce:FUNCtion CURRent
:SOURce:CURRent:RANGe 1e-01
To set the range to 20 V for the voltage function, you would send:
:SOURce:FUNCtion VOLTage
:SOURce:VOLTage:RANGe 20
The SCPI commands that set up the measurement functions are in the SENSe subsystem.
The sense commands are also specific to each measure function (voltage, current, or resistance). For
example, to set the NPLC cycles to 0.5 for the current measurement function, you would send:
:SENSe:CURRent:NPLCycles .5
For the voltage measurement function, you would send:
:SENSe:VOLTage:NPLCycles .5
For the resistance measurement function, you would send:
:SENSe:RESistance:NPLCycles .5
To make a measurement, you send the MEASure:<function>? command. For example, to make a
current measurement, send the command:
:MEASure:CURRent?
To make a voltage measurement, send the command:
:MEASure:VOLTage?
To make a resistance measurement, send the command:
:MEASure:RESistance?
For detailed application examples that use the SCPI command set, see the User's Manual.
Command descriptions are provided in the SCPI command reference (on page 6-1).
Source and measure using TSP commands
The TSP commands that set up the source functions begin with smu.source.
The source commands are specific to each source function (voltage or current). For example, to set
the range to 100 mA for the current source function, you would send:
smu.source.func = smu.FUNC_DC_CURRENT
smu.source.range = .1
To set the range to 20 V for the voltage function, you would send:
smu.source.func = smu.FUNC_DC_VOLTAGE
smu.source.range = 20
