Two Grades, each with defined accuracy

For use with Vector Network Analysers – 1.14 GHz to 500 GHz.

Two grades of calibration kits and components are available that enable VNA users to select the one most suitable for the analyser type and measurement requirement. Various manufacturing techniques are employed and selected according to waveguide size and required accuracy.

Critical components in each grade of kit have defined accuracies – a feature unique to Flann Waveguide Calibration Kits. Flann calibration kits contain all the components necessary to conduct TRL calibrations with modern VNAs configured for waveguide measurements. A typical kit would include waveguide to coax adaptors up to and incl. WG22, fixed terminations, a sliding termination, offsets, flush shorts and a waveguide section. Kits are supplied in a fitted hardwood case complete with connecting hardware, and USB Drive incl. handbook.

Note 1 – Offsets

The length of each Flann offset section is designed to provide a phase balanced response over the recommended frequency range. Fractional wavelengths are specified with respect to a wavelength λg° where:-

λglf is the waveguide wavelength at the lowest frequency of the operating range and λghf is the waveguide wavelength at the highest frequency of the operating range.

Flann Calibration Kits have been developed in close cooperation with manufacturers and users of network analysers. Kits are available in each of the two grades, suitable for analyser configurations requiring TRL, OOL and LRL calibration kit styles. The selection of a calibration kit and its contents is largely dictated by the combination of analyser model, test set model and type of calibration routine to be implemented, i.e. full 12 term, single path 2 port, reflection only or TRL/LRL.

OOL – Offset/Offset/Load
TRL – Thru/Reflect/Line
LRL – Line/Reflect/Line

The waveguide Calibration Kits contain the components necessary to fully calibrate Vector Network Analysers. Flann Calibration Kit components are available individually or to supplement standard kits. Specialised Calibration Kits or components for use with alternative measurement systems, such as six port reflectometers, are also available. Full details are available on request.

The specifications and capabilities of network analysers are subject to constant evolution and development. Please consult us for Calibration Kit applications assistance if required.

Note 2 – Flanges

Flann Calibration Kit components are fitted with “Precision Flanges” that are fully compatible with standard flanges whilst providing enhanced accuracy and repeatability. Kits are also available fitted with alternative flange styles or special flanges to customer specification. Details on request.

Note 3 – Waveguide to Coax Adaptors

The Waveguide to Coax Adaptors supplied with Flann Calibration Kits are of sufficient length to ensure the decay of unwanted evanescent modes.
