sintgX

This command makes an integrated measurement for every point in a sweep.

int sintgi(int instr_id, double *result);

int sintgv(int instr_id, double *result);

Used this command to create an entry in the measurement scan table. During any of the sweeping

commands, a measurement scan is performed for every force point in the sweep. During each scan,

a measurement is made for every entry in the scan table. The measurements are made in the same

order in which the entries were made in the scan table.

The sintgX command sets up the new scan table entry to make an integrated measurement. The

measurement results are stored in the array, specified by the result parameter. Each time a

measurement scan is made, a new measurement result is stored at the next location in the results

array. If the scan table is not cleared, making multiple sweeps will continue to add new measurement

results to the end of the array. Care must be taken that the results array is large enough to hold all

measurements that are made before the scan table is cleared. The scan table is cleared by an explicit

call to the clrscn command, or implicitly when the devint or execut command is called.
