Keysight R, Q, U, V, and W11644A 4-5
Use, Maintenance, and Care of the Devices
Connections
Connections
Good connections require a skilled operator.
Slight errors in operator
technique can have a significant effect on measurements and measurement
uncertainties. The most common cause of measurement error is poor
connections.
The following procedures illustrate how to make good connections.
Waveguide Devices
Precision Flanges
A precision flange has four corner screw holes and two precision alignment
. A non-precision flange has only four corner
screw holes.

Place the slip pins in the top and bottom holes of one flange, as shown in
.
IMPORTAN! Unlike threaded devices, the WR-28, WR-22, WR-19, WR-15,
and WR-10 waveguide mating planes are flanges (often precision) that you
must carefully screw together. Always connect waveguide in the same
flange orientation. For example, use the label as a reference and always
connect a device with the label facing the same direction.
