Example
double leakage;
.
.
limiti(SMU1, 1.0e-06); /* Limit the maximum current */
/* 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
avg
X
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).
Usage
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
);
instr_id
The instrument identification code of the measuring instrument
result
The result name of the array to receive readings; the array must be large enough to
hold the readings
numrdg
The number of readings to return in the array
delay
The delay between points to wait (in seconds)
timerid
The device name of the timer to use (
0
= no timer data)
timerdata
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
Details
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
bmeas
X
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.
