Calibration Devices and Their Use
The P, K, and X11644A waveguide calibration kits contain termination load, standard
sections, shim, and short.
For measurement convenience, these kits contain either 7 mm coax-to-waveguide adapters
for P-band and X-band, or 3.5 mm coax-to-waveguide adapters for K-band. The adapters
are intended for adapting coaxial test sets to waveguide.
The following briefly describes the design and construction of all the calibration kit
devices.
Short
A short is also called a flush short. It is connected directly to the test port, or used as an
offset short when combined with the ¼ wavelength shim.
Termination
A termination is also called a load. It is connected directly to the test port, or used as an
offset load when combined with the ¼ wavelength shim.
¼ Wavelength Shim
A ¼ wavelength shim is also called an offset, or ¼ wavelength section. The shim is
terminated by the short, fixed load, or the second test port of the analyzer.
Standard Section
A standard section is used to check system operation after you complete a calibration.
