KI590ulib user library
The user modules in the KI590ulib user library are used to control the 590 C-V Analyzer. These
user modules are summarized in the table below. Also listed in the table are names of the user test
modules (UTMs) and actions in Clarius that use the user modules.
KI590ulib user modules
User module UTM or action name Description
CableCompensate590 (on page B-
12)
cable-compensate in
the ivcvswitch project
Performs cable compensation using known
capacitance source values.
Cmeas590 (on page B-14)
590-cmeas
Makes a single capacitance measurement.
CtSweep590 (on page B-17)
590-ctsweep
Makes a capacitance versus time
measurement.
CvPulseSweep590 (on page B-21)
590-cvpulsesweep
Makes capacitance versus voltage
measurements using a pulse sweep.
CvSweep590 (on page B-27)
590-cvsweep
Makes capacitance versus voltage
measurements using a staircase sweep.
DisplayCableCompCaps590 (on page
B-31)
display-cap-file in
the ivcvswitch project
Places capacitance source values in a
spreadsheet.
LoadCableCorrectionConstants (on
page B-33)
n/a
Reads the cable compensation parameters for
the range and frequency specified from the
cable compensation file and sends these
parameters to the 590.
SaveCableCompCaps590 (on page
B-34)
save-cap-file
in the
ivcvswitch project
Saves entered capacitance source values in a
file.
KI595ulib user library
The user modules in the KI595ulib user library are used to perform Q/t sweeps and C-V sweeps
using the Keithley Instruments 595 Quasistatic C-V Meter. These user modules are summarized in
the table below.
KI595ulib user modules
User module Description
CVsweep595
Performs a quasistatic C-V sweep between the start voltage and the stop
voltage. The data returned is the source voltage, measured capacitance, Q/t
current, and timestamp on each measurement.
QTSweep595
Makes 20 Q/t current and capacitance measurements with various time delays
that are spaced between 0.07 s and the maximum delay. You can analyze and
plot the resulting values to determine the optimum delay time to use during the
C-V sweep. The optimum delay time is the time when Q/t reaches the system
leakage level.
