Model 4200A-SCS Parameter Analyzer Reference Manual

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.

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.

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

DSA, ±BBB.BBBB

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.

This command string sets VS1 to output 20 V.
