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 17.
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 performance of your Site Ana-
lyzer. Using a non-Bird phase stable cable may
decrease and degrade the accuracy of the system.
Select the Measurement Units
You can select units before or after making a measure-
ment. When making a match measurement, you can
select one of three units for the Y (vertical) scale,
•
VSWR (ratio)
•
Rtn Loss (dB)
•
Cbl Loss (dB)

ment Frequency, page 20)
