Using the Test Set Module Stand

Using the Test Set Module Stand
Attach the test set module to a stand for vertical and horizontal level
adjustment. These adjustments help to align port 1 and port 2 during device
testing.
Adjustable Feet
The adjustable feet located at each corner of the stand allow limited
(approximately 13 mm (1/2 inch)) vertical adjustment. Move port 1 and port
2 together just enough to judge their relative alignment. Adjust the feet on
one of the modules until both modules are aligned vertically so they can be
connected together. The waveguide components must be coplanar.
Thumbwheel
The thumbwheel is on the elevator portion of the stand and allows for
vertical adjustment of the module (Figure 5-3 on page 5-5). The range of
adjustment is approximately 31.75 mm (1.25 inch).
Do not use the thumbwheel to raise the module beyond 38.1 mm
(1 1/2 inches). The elevator assembly may disengage from the rest of the
stand assembly past this dimension.
Slide Lever
The slide lever locks/unlocks the test set module stands horizontal
movement (see Figure 5-3 on page 5-5). The module is locked in place when
the slide lever is pushed toward the rear of the module, and unlocked when
the slide lever is pushed toward the front of the module. The range of
horizontal adjustment is approximately 152 mm (6 inches). This adjustment
is especially useful when quick setup and measurement are important and
the mm-wave modules must remain stable.
