double leakage;

/* to 1 µA */

forcev(SMU1, 10.0); /* Force 10 V across the DUT */

delay(100); /* Delay 100 ms to allow for */

/* device settling */

avgi(SMU1, &leakage, 5, 0.01); /* Average 5 readings, delay */

/* 10 ms per measurement */

This example illustrates how to use the avgX command to make five current readings and return the

average of the measurements to the variable leakage.

bmeasX

This command makes a series of readings as quickly as possible. This measurement mode allows for waveform

capture and analysis (within the resolution of the measurement instrument).

int bmeasi(int instr_id, double *result, long numrdg,

double delay, int timerid, double *timerdata);

int bmeasv(int instr_id, double *result, long numrdg,

double delay, int timerid, double *timerdata);

This command collects data using the presently selected range. The measurement range is typically

the same as the force range. If you need a different range, you must change the measurement range

before calling the bmeasX command.

When used with the time module, the measurements and the times for each measurement are stored.

The specific timer is defined in the command, and the time array is returned with the results array.

The instrument identification code of the measuring instrument

The result name of the array to receive readings; the array must be large enough to

hold the readings

The number of readings to return in the array

The delay between points to wait (in seconds)

The device name of the timer to use (0 = no timer data)

The array used to receive the time points at which the readings were made; if

timerID = 0, the timer is not read and this array is not updated; if used, the array

must be large enough to hold the readings
