Section 9: Keithley External Control Interface (KXCI)

This command defines channels that are used as voltmeters.

VMA, 'BBBBBB'

KXCI allows up to eight source-measure units (SMUs) to function solely as voltmeters. You can use

any channel for any voltmeter function between VM1 and VM9. For example, in a system containing

four SMUs, you can use SMU3 as VM7.

If you do not define one of the 4200A-SCS SMUs to emulate a VM, attempts to measure voltages

through the nonexistent VM result in data values of 9.000e+37.

If nothing is specified after the prefix and channel number, the channel is not used.

To measure voltage using the 4145B VM1...VMn function, define one of the 4200A-SCS SMUs to

This command string defines the channel used for VM1 (specifies the name VM1).
