Use of the Kirkby Microwave calibration kits on the Agilent/Keysight ENA series of VNAs
The Kirkby Microwave VNA calibration and verification kits work well with all Agilent or Keysight ENA series vector network analyzers. The process of setting up an ENA depends on the age of
the model of ENA.
On early models, it is necessary to enter the coefficients from the front panel. There's no way to load the vector network analyzer calibration kit coefficients from a file.
Kirkby Microwave always provide the coefficients in a human readable text file, but
you will need to enter the coefficients manually into the VNA. These is simply no other way on these early instruments, as is indicated on the Keysight website.
It is inexplicable to us why Agilent did this, but that's a fact!
More recent models of the ENA series, such as a
E5071C, can read a .ckx file. Kirkby
Microwave supply appropriate .ckx files with all coaxial calibration kits (SMA or N) sold. We generate these ckx files automatically, taking a small fraction of one second.
For waveguide calibration kits we do not have an automated process, but need to create the files manually on an ENA, but that is no problem.
The latest ENA models use the same software as the PNA series, so use the same file, which has an extension of .xkt. We create these files too,
and include with every coaxial calibration kit sold.
