A range of Double Ridge Calibration Kits has been added to the company’s extensive selection of rectangular waveguide Kits.

The Double Ridge Calibration Kits contain the standards and components required to fully calibrate VNA’s configured for waveguide measurements. Kits are available to suit all models of VNA’s in double ridge waveguide sizes from 3.5 GHz to 40 GHz.

A kit would typically include:

• Waveguide to Coaxial Adaptors
• Fixed Terminations
• Flush Short
• Offsets
• Offset Shorts
• Sliding Termination (optional – depending on analyser type and calibration method)
• Data disc, hardware and handbook

All the components are supplied in a fitted hardwood case.
