Details
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...VS
n
function, define one of the 4200A-SCS SMUs to
emulate the VS.
Example
VS1, 'VS1', 1
This command string sets up the channel used by VS1 to perform a voltage sweep.
