hp4294ulib user library reference
The user modules in the hp4294ulib user library are used to calibrate and control the HP Model
4294 IMP meter. Subroutines are provided to perform voltage or frequency sweeps. These user
modules are summarized in
Details for each of the user modules follow the table.

An HP 4294 measurement is valid only if proper calibrations are performed prior to it. 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.

NOTE:
CvSweep4294 user module
User module description
The CvSweep4294 routine performs a capacitance vs. voltage (C-V) sweep using the HP 4294
IMP meter.
general, the HP 4294 outputs a linear staircase voltage sweep. The shape of the staircase is
configured by user inputs for the starting voltage, ending voltage, and number of points in the
sweep. A capacitance measurement is performed on each step of the sweep.

The HP 4294 is added to the Model 4200-SCS test system using KCON. For
details, see Keithley CONfiguration Utility (KCON)
Details on HP 4294 operations are provided in the documentation provided by HP
for the IMP meter.
