Positioner Installation
Proper installation of the Azimuth Positioner (AP) unit directly affects
performance of the positioning system as well as the accuracy of the test results.
1. Uncrate all parts. Check all parts for any shipping damage. Ensure a
clear area is available to assemble the AP unit safely.
Do not discard packing material until the AP is fully assembled and
correct operation is verified.
The Azimuth Positioner consists of:
• Variable speed turntable
• Three Lexan pegs
• Lossy foam absorber (three pieces) to cover the top of the turntable
• Custom vertical column
• Rotary joint kit including all internal RF cabling
Customer provides RF cabling to the top of the support column.
2. The center of rotation for the AP must intersect the line through the
bore sight of the measurement antenna. It is recommended that a 5-
beam laser level be utilized to verify the alignment and location.
