Programming Examples

Sampling Measurements

Table 3-16 explains example subprogram that performs linear sampling

measurement. This example measures current that flows to resistors R1 and R2, and

then calculates the resistance.

Table 3-16 Sampling Measurement Example

Line Description

2 to 11 Declares variables used through the project. And sets the proper values.

13 to 23 Declares variables used to set the source output, and sets the value.

24 to 31 Declares variables used to read the measurement data.

33 Sets the data output format. The source output data will be also returned.

34 Sets the SMU filter on.
