LSSI
The LSSI command sets the synchronous current source for the linear search
measurement (MM14). The synchronous source output will be:
Synchronous source output = polarity × LSI source output + offset
where the LSI source output is the output set by the LSI command.
This command setting is cleared by the LSV/LSI command.
Execution
Conditions
The LSI command must be entered before this command.
If Vcomp value is greater than the allowable voltage for the interlock open
condition, the interlock circuit must be shorted.
Syntax LSSI chnum,polarity,offset[,Vcomp]
Parameters chnum : SMU synchronous source channel number. Integer expression. 1 to 10
or 101 to 1001. See Table 4-1 on page 4-16.
polarity: Polarity of the LSSI output for the LSI output.
0 (negative): LSSI output = −LSI output + offset
1 (positive): LSSI output = LSI output + offset
offset: Offset current (in A). Numeric expression. See Table 4-6 on page 4-23,
Table 4-8 on page 4-25, or Table 4-11 on page 4-27 for each
measurement resource type.
Both primary and synchronous search sources will use the same output
range. So check the output range set to the LSI command to determine
the synchronous source outputs.
Vcomp: Voltage compliance value (in V). Numeric expression. If you do not
specify Vcomp, the previous value is set.

OUTPUT @B1500;"LSSI 1,1,1E-6,5"
See Also For the source output value, output range, and the available compliance values, see
Table 4-6 on page 4-23, Table 4-8 on page 4-25, or Table 4-11 on page 4-27 for each
measurement resource type.
