Keithley 4200A-SCS Reference Manual

Model 4200A
-SCS Parameter Analyzer Reference Manual Section 9: Keithley External Control Interface (KXCI)
4200A-901-01 Rev. C / February 2017 9-41
Details
For every channel that is configured as a SMU, you must select the source mode (voltage or current)
and source output range, and set the output and compliance values.
With the voltage source mode (DV) specified in the command string, the output value is in volts. For
the current source mode (DI), the output value is in amps.
With the voltage source mode (DV) specified in the command string, you are setting the current
compliance. For the current source mode (DI), you are setting the voltage compliance. When
sourcing voltage, note that if you specify a compliance current that is below the minimum-allowable
value (1 pA with a preamplifier installed and 100 nA without a preamplifier), KXCI sets it to the
minimum allowable value.
Example
DV1, 1, 10, 10E-3
This command string configures SMU1 to source 10 V on the 20 V source range and sets current
compliance to 10 mA.

DS
This command specifies the channel number and the voltage output value for each voltage source.
Usage

Output voltage value: −200.00 to +200.00
Details
KXCI allows up to nine source-measure units to function solely as voltage sources. You can use any
channel for any voltage-source function between VS1 and VS9. For example, in a system containing
four SMUs, you can use SMU2 as VS5.
The assigned n value for a voltage source (VSn) or voltmeter (VMn) depends on how instruments are
mapped in KCon.
Example
DS1, 20
This command string sets VS1 to output 20 V.
