Filter
Enable or disable the analog filter, which can minimize the amount of noise that
appears in the readings; however, it increases the measurement time:
▪ Disable the filter: 0
▪ Enable the filter: 1
Count
The number of readings per sweep: 1 to 1350
ReadingRate
Selects the reading rate used to acquire the measurements: 0 to 4; see Details
C
Output: The measured array of capacitance values
Csize
Set to a value that at minimum is equal to the Count; if in doubt, set to 1350
G_or_R
Output:
▪ When the parallel measurement model (1) is selected, G_or_R is the
measured conductance
▪ When the series measurement model (0) is selected, this is the measured
resistance
G_or_Rsize
Set to a value that at minimum is equal to the Count; if in doubt, set to 1350
T
The array of time stamps for each measurement step
Tsize
Set to a value that at minimum is equal to the Count; if in doubt, set to 1350
Details
This user module performs a capacitance versus time (Ct) sweep. The figure below shows the default
parameters for the ctsweep-590 UTM, which uses the CtSweep590 user module.
