CtSweep82 user module
The CtSweep82 user module measures capacitance as a function of time at a certain bias.
Usage
status = CtSweep82(int Frequency, double Default_Bias, double Stress_Time, double
Test_Bias, double Sample_Time, int Reading_rate, int Num_Points, int Range590,
int Model590, int Filter590, char *CabComFile, int OffsetCorrect, char
*instr_id, int InputPin, int OutPin, double *CHF, int CHF_ArrSize, double
*G_or_R, int G_or_R_ArrSize, double *Time, int Time_ArrSize);
Returned values are placed in the Analyze sheet; see Details
The measurement frequency:
• 100 kHz: 0
• 1 MHz:
DC bias applied before and after a C-t sweep (−20 V to +20 V)
Duration of the default bias before test bias is applied (0.001 s to 65 s)
Voltage bias for capacitance measurements (−20 V to +20 V)
Time delay between each sampling measurement (0.001 s to 65 s)
The reading rate used to acquire the measurements (1 to 4; see Details)
Number of sampling points (1 to 1350)
The measurement range for the 590 (1 to 4; see Details for valid range values)
The measurement model to use for high frequency measurement:
• Parallel mode: 0
• Series model:
Enable or disable the analog filter; see Details:
• Disable the filter: 0
•
The complete name and path for the cable compensation file; see Details
Enable or disable an offset correction measurement:
• Disable offset correction: 0
•
Enable offset correction: 1
KCon instrument ID; default is CMTR1; can be CMTR1 to CMTR4, depending on your
system configuration
The DUT pin to which the 5951 input terminal is attached (−1 to 72); if a value of
less than 1 is specified, no switch matrix connections are made; see
