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.

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 (
VS
n
) or voltmeter (
VM
n
) depends on how instruments are
mapped in KCon.
Example
DS1, 20
This command string sets
VS1
to output 20 V.
