System mode commands

This command specifies the name and selects the source function for each voltage-source channel.

VSA, 'BBBBBB', C

KXCI allows up to eight 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.

For each voltage source that is used, you must specify a name and select the source function. The

VAR1 function performs a voltage sweep that is synchronized to the steps of VAR2. The VAR1

source function performs a linear or logarithmic voltage sweep. The VAR1 sweep is done whenever

VAR2 goes to a new step value. The VAR1' function is the same as VAR1 except that each step of

the sweep is scaled by a specified ratio (RT) and offset (FS).

The constant source function outputs a fixed (constant) voltage source value. More information on

source functions is available throughout this section.

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

To source voltage using the 4145B VS1...VSn function, define one of the 4200A-SCS SMUs to

emulate the VS.

VS1, 'VS1', 1

This command string sets up the channel used by VS1 to perform a voltage sweep.
