Registered office: Stokes Hall Lodge, Burnham Rd, Althorne, Essex, CM3 6DT.The size of a deck of cards, the USB-powered Planar R140 VNA is a 1-port VNA capable of measuring S 11 from 85 MHz to 14 GHz and designed for use with with any Windows PC or laptop.
Kirkby Microwave Ltd is registered in England and Wales, company number 08914892. The software looks quite similar to the Agilent PNA software too! The offset delays of the opens and shorts are given as delays in ps.
Where the capacitance is in Farads and the frequency in Hz. The fringing capacitance of an open is assumed to be given by the 3rd order polynomial:Ĭ fringing=C0x10 -15 + C1x10 -27f + C2x10 -36f 2+C3x10 -45f 3 Measured, and their coefficients computed, Kirkby Microwave will run the Copper Mountain software in demo mode to create the necessary files.Ĭopper Mountain follow the same methods as HP/Agilent/Keysight for defining their calibration kits. Kirkby Microwave can supply the files for either type of Copper Mountain VNAs. Since no Copper Mountain vector network analyzer will have the correct coefficients for a Kirkby Microwave calibration kit, these must be entered as a user-defined calibration kit. Installing the calibration kits definitionsīefore using a vector network analyzer it is absolutely essential that the VNA has the correct calibration constants for a calibration kit. The more expensive models, which are full VNAs with S-parameter test sets, use a different file format.
However, weĬan produce files readable by any type of Copper Mountain VNA. Unfortunately, at the time of writing (July 2018), Copper Mountain use a different format of calibration kit files for different models. The page gives you the information needed to use Kirkby Microwave calibration and verification kit on Copper Mountain vector network analyzers (VNAs).
