Csize
Set to a value equal to or greater than the number of voltage steps in the sweep or
equal to ((
LastBias − FirstBias
) /
StepV
) + 1
V
Output: The array of bias voltages used
Vsize
Set to a value equal to or greater than the number of voltage steps in the sweep or
equal to ((LastBias − FirstBias) / StepV) + 1
G_or_R
Output:
• When the parallel measurement model (0) is selected, G_or_R is the
measured conductance
• When the series measurement model (1) is selected, this is the measured
resistance
G_or_Rsize
When this function is called from a Clarius UTM, this parameter is fixed at 1350
T
The array of time stamps for each measurement step
Tsize
When this function is called from a Clarius UTM, this parameter is fixed at 1350
Details
This user module performs a capacitance versus voltage staircase sweep. The figure below shows
the default parameters for the 590-cvsweep UTM, which uses the CvSweep590 user module.
