RF & Microwave Engineering

New • RF Instrumentation • Python Desktop Application

Automated Electromagnet & VNA Measurement System

Built a Windows desktop application that controls an electromagnet power supply and a Keysight PNA-X vector network analyzer over GPIB. It runs automated magnetic-field sweeps, measures S-parameters at every field point, and saves all data as it is acquired. Built for measuring field-tunable devices such as YIG filters.

Key Contributions

  • Central safety layer enforces a maximum-current limit on every current command, with a software voltage monitor that triggers an emergency stop.
  • Gradual current ramping to avoid inductive kickback from the coil, and current-to-field calibration with hysteresis support.
  • Automated sweeps measuring S11, S21, S12, and S22, with live plots, color maps, and HDF5/CSV data saving.
  • Simulation mode with a shared instrument model, so the app runs without hardware; 43 automated unit tests.
