smeasX
This command allows a number of measurements to be made by a specified instrument during a sweepX command. The
results of the measurements are stored in the defined array.
Usage
int smeasi(int instr_id, double *result);
int smeast(int instr_id, double *result);
int smeasv(int instr_id, double *result);
int smeasc(int instr_id, double *result);
int smeasg(int instr_id, double *result);
instr_id
The instrument identification code of the measuring instrument
result
The floating point array that stores the results
Details
This command is used to create an entry in the measurement scan table. During any of the sweep
commands, a measurement scan is done 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 smeasX command sets up the new scan table entry to make an ordinary measurement. T
he
m
easurement 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 result
array. If the scan table is not cleared, doing multiple sweeps continues adding 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 command is called.
