4: Sourcing and measuring 2470 High Voltage SourceMeter Instrument
4-32 2470-901-01 Rev. A / May 2019
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 send:
:SENSe:CURRent:NPLCycles 0.5
For the voltage measurement function, you send:
:SENSe:VOLTage:NPLCycles 0.5
For the resistance measurement function, you send:
:SENSe:RESistance:NPLCycles 0.5
To make a measurement, you send the MEASure:<function>? command. For example, to make a
c
urrent 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 2470 User's Manual.
Command descriptions are provided in the SCPI command reference (on page 12-1
).
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 = 0.1
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
The TSP commands that set up the measurement functions begin with smu.measure.
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 send:
smu.measure.func = smu.FUNC_DC_CURRENT
smu.measure.nplc = 0.5
