Chapter 2 Calibration
Calibration Accessories

Calibration Combination (Cal Combo) which contains:
One 50 ohm load
One Open standard
One Short standard
Note: When using a test cable connected to the Site Analyzer, attach
the Cal Combo to the end of the cable during calibration.

Test Cable (optional) – A phase-stable cable will provide consistent,
reliable results.
Note: When using an extension cable, a phase stable cable is needed
to ensure performance and accuracy. Bird offers optional phase stable
cables that will not degrade the performance of the Site Analyzer.
Using a non-Bird phase stable cable may decrease and degrade the
accuracy of the system.
Calibrating the Site Analyzer
For best results, set the frequency and calibrate the Bird Site Analyzer immedi-
ately before taking measurements.
Note: When calibrated, the Site Analyzer’s main screen will display
“Calibration: FULL”. When uncalibrated, the Site Analyzer’s main
screen will display “Calibration: OFF”.
Note: Calibration is performed at the highest number of data points
(949 points) and the calibration graphs are displayed using the cur-
rently selected display method (envelope, maximum, or minimum).
