Calibration Devices and Their Use
The R, Q, U, V, and W11644 waveguide calibration kits may contain some or all
of the following: short, standard section, termination loads, wavelength shim,
and waveguide straights.
The following briefly describes the design and construction of all the
calibration kit devices.
IMPORTANT! To ensure calibration accuracy, you must use the alignment
slip pins in the precision flanges. Refer to
4-5.
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.
Standard Section
A standard section is used to check system operation after you complete a
calibration.
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.
Waveguide Straight Section (verification device)
A waveguide straight is included as a system verification device. Be sure to
keep it protected from wear and damage. When using it, always connect the
same side, in the same orientation, for consistent and accurate mating.
Waveguide Straight Section (port 1 and 2)
Two waveguide straights, provided in this kit, are used as port 1 and port 2
measurement planes when properly connected to the directional couplers.
Because these straight sections are used as port 1 and port 2 for device
