HOMER Hot Measurement System - R&D High Power Vector Impedance Analyzer

The HOMER™ Hot Measurement Analyzer is high power vector impedance and power analyzer serving for effective and easy monitoring process parameters in microwave heating, semiconductor/FDP fabrication and other industrial applications, including plasma.

The system is designed for CW, high-ripple ("Rectified") and pulsed generator power waveforms. Under the full-power operating conditions of magnetron-based microwave generators, Homer Analyzer measures both magnitude and phase of reflection coefficient as well as incident, reflected, absorbed powers and frequency.

It can help reduce equipment manufacturing costs controlling the quality of a fabrication process.

Homer Analyzer comes with its own firmware and documentation. It can be controlled from a personal computer via RS232 or CAN Bus interface. Versions for 900 MHz and 2.45 GHz ISM bands exist.

Modes of Power Sampling
Homer supports three modes of power waveform sampling, named CW, Rectified, and Pulsed.
  • CW mode is applicable to unmodulated microwave signals with output power ripple not exceeding 15% of peak value.
  • Rectified mode is designed for slowly pulsing microwave signals (up to 400 Hz repetition rate). Such signals are typical for magnetrons powered by low-cost power supplies which incorporate simple half-wave or full-wave rectifiers.
  • Pulsed mode option is intended for sampling fast pulse-modulated microwave signals with pulse widths down to 100 µs and repetition period up to 100 ms.
Rectified and Pulsed modes provide both instantaneous and average values of reflection coefficient and power.
