rtfary

This command returns the force array determined by the instrument action.

int rtfary(double *results);

This command eliminates the need to calculate the forced array in the application.

When this command is used with one of the sweep routines, you can determine the exact forced

value for each point in the sweep.

When the test sequence is executed, the sweep command initiates the first step of the voltage or

current sweep. The sweep then logs the force point that the buffer specified by the rtfary

Locate the rtfary command before the sweep. The number of data points returned by the rtfary

command is determined by the number of force points generated by the sweep.

Refer to the examples for the smeasX and sweepX commands.

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

int savgi(int instr_id, double *result, long count, double delay);

int savgv(int instr_id, double *result, long count, double delay);

The floating point array where the force values are stored

The instrument identification code of the measuring instrument

The floating point array where the results are stored

The number of measurements made at each point before the average is computed

The time delay in seconds between each measurement within a given ramp step
