6: Clarius Model 4200A-SCS Parameter Analyzer
6-310 4200A-901-01 Rev. C / February 2017
HP4294ulib user library
You can use the user modules in the HP4294ulib user library to calibrate and control the Keysight
Model 4294 IMP meter. Subroutines are provided to perform voltage or frequency sweeps. These
user modules are summarized in the following table.
HP4294ulib user modules
User module Description
Performs a capacitance versus voltage sweep.
Performs a frequency versus impedance sweep.
Performs LOAD calibration.
Performs OPEN calibration.
Performs PHASE calibration.
Performs SHORT calibration.
A Keysight 4294 measurement is valid only if proper calibrations are performed before the
measurement is made. The user may run calibration at any time.
A recommended calibration sequence is as follows:
1. Move prober to an OPEN calibration structure.
2. Call PhaseCal4294.
3. Call OpenCal4294.
4. Move prober to a SHORT calibration structure.
5. Call ShortCal4294.
6. Move prober to a LOAD calibration structure.
7. Call LoadCal4294.
The Keysight 4294 is added to the 4200A-SCS test system using KCon. For details, see Keithley
Configuration Utility (KCon) (on page 7-1).
Details on Keysight 4294 operations are provided in the documentation provided by Keysight for the
IMP meter.
