MATLAB Tool for the Impedance Analyzer 4294A

This MATLAB tool offers different functions for working with the HP/Agilent/Keysight 4294A impedance analyzer.

The following functions are implemented:

• Read the measured data (ASCII format)
• Get the device tolerances (amplitude and angle)
• Compute the tolerances for the measured data

The following configuration is considered:

• Bandwidth setting can be chosen
• Oscillator voltage can be chosen
• The bias level is assumed to be zero
• The standard 16047E adapter is used

Example

The following examples are included:

• run_device_tol.m - Get and plot the device tolerances
• run_meas_tol.m - Read a measurement and compute the tolerances

Compatibility

The tool is tested with the following MATLAB setup:

• Tested with MATLAB R2018b / 2019a / 2024b
• No toolboxes are required.
• Compatibility with GNU Octave not tested but probably easy to achieve.
