Programming example #3

Performs a single frequency sweep shown in the following figure.

CpGp is measured on each frequency step of the sweep.

Test parameters:

AC drive voltage = 15 mV

Measure mode = CpGp

Measure range = Auto

Start frequency = 100 kHz

Stop frequency = 300 kHz

Number of frequency steps = 3 (this value is returned from the command to the NumPts variable,

and not passed by the user)

Delay = 50 ms

double result1[6], result2[6], forceArray[6];

long NumPts;

setlevel(CVU1, 15e-3);

setauto(CVU1);

smeasz(CVU1, KI_CVU_TYPE_CPGP, KI_CVU_SPEED_NORMAL, result1, result2);

rtfary(forceArray);
