Features
- Models cover bands from 1.14 GHz to 500 GHz
- Precision Grade (series 760) or Metrology Grade (series 761)
- Standard kits for TRL or OOL calibration
- Customised kits available to include the components needed for user-specific calibrations
Flann calibration kits are suitable for use with almost all models of Vector Network Analyser and for use over any rectangular or double-ridged (WRD) waveguide band from 1.14 GHz to 500 GHz.
Two grades of calibration kit are available, allowing VNA users to select the one most suitable for the analyser type and measurement accuracy required. Critical components have defined accuracies in terms of mechanical tolerance, and the manufacturing techniques employed are carefully selected according to waveguide size and required accuracy.
- Precision Grade: Designed for users requiring high quality components for excellent calibration in any commercial or industrial laboratory.
- Metrology Grade: Have even more precise dimensional tolerances for the very best calibrations demanded by the most critical applications.
These calibration kits contain all the components necessary to conduct a TRL (Thru-Reflect-Line) calibration as standard, or other waveguide calibrations, including OOL/LRL and custom types upon request.
Note: As operating frequencies increase, the wavelength decreases proportionally. Calibration Kit, offsets are typically designed as 1/4 wavelength; however, at higher frequencies, the thinness and fragility of the offsets can be problematic over repeated use. Flann offer 3/4 and 5/4 wavelength offsets as standard to overcome this challenge ensuring repeatable, reliable calibrations.
Specifications
Every kit comes with Hardwood Case, USB Drive, including Handbook, Flange Bolts etc, Precision Flange Dowels.

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.
