Before you order
Match the kit to the instrument and fixture
Adapter interfaces
The kit description includes two waveguide-to-coaxial adapters. Connector options include N, SMA, 2.92 mm, 1.85 mm and 1.0 mm, depending on the model.
Components and offset lengths
The kit includes a termination, short and waveguide offset sections. The matrix lists the actual offset thicknesses, rather than one set of dimensions for every band.
Calibration files
The source lists a Calibration Coefficients Definition Sheet and Keysight-compatible data. Include the VNA model and software version so the required format can be checked.
If you only need individual components, compare waveguide shorts and shorting plates and waveguide-to-coaxial adapters.
For the rest of your setup
Does your method need a sliding load?
Lower-band kit options may include a sliding load. Specify the intended calibration method and confirm the component list for the exact kit you need.

Questions before ordering
Can I use the kit with any VNA?
The connector, measurement band and calibration definitions must match the instrument setup. Send the VNA model and required data format before ordering.
Can I replace only one calibration component?
Identify the existing kit and the missing component, including flange code and offset dimensions. The component can then be checked against the original kit specification.
