Line Description
45 Resets time stamp.
46 Calls the check_err subprogram (shown in Table 3-1) to check if
an error status is returned for the previous line.
48 to 49 Applies voltage to device.
51 to 56 Declares a variable, and defines the value. This variable is used
for the step value of the secondary sweep source.
58 to 59 Declares a variable, and defines the value. This variable is used
for the output value of the secondary sweep source.
61 Sets the array counter i to 0.
