Calibrate the Site Analyzer
If you need to use an extension cable to connect the Site Analyzer to
the system, connect the extension cable to the antenna test port on the
Site Analyzer and then connect the Bird Cal Combo to the end of the
extension cable. Follow the calibration procedure in
Chapter 2, Calibration, page 15.
Note: When using an extension cable, you should use a
phase stable cable to ensure performance and accuracy. Bird
offers optional phase stable cables that will not degrade the per-
formance of your Site Analyzer. Using a non-Bird phase stable
cable may decrease and degrade the accuracy of the system.
