resv
This subroutine measures two-terminal resistance (force V, measure I).
Usage
double resv(int hi, int lo, int sub, double v)
hi
Input
The HI pin of the device
lo
Input
The LO pin of the device
sub
Input
The substrate pin of the device
v
Input
The forced voltage, in volts
Returns
Output
The calculated resistance:
 1.0E+20 = Measured current is < 10 pA
 4.0E+21 = Measured current is within 98 % of the 200 mA current
limit
Details
This subroutine calculates the resistance of a two-terminal resistor by forcing a specified voltage and
measuring the resulting current.
If a positive substrate pin is specified, the substrate is grounded. If a positive substrate pin is not
specified, the substrate is left floating.
Source-measure units (SMUs)
SMU1: Forces V, maximum current limit, measures I
Example
result = resv(hi, lo, sub, v)
