Chapter 3 Measure Match Mode
Match measurement verifies and monitors the match conditions in the
antenna system at various frequencies. The results are shown on an x-
y graph. Frequency is shown on the x-axis and return loss, cable loss,
or VSWR is shown on the y-axis.
Before you make a match measurement, be sure that you have a Bird
Calibration Combination (Cal Combo) and all necessary cables and
adapters of the correct size and connector type.
This chapter describes how to make a match measurement and pro-
vides step by step instructions. In addition, this chapter describes how
to set and move markers. For information and instructions to save and
recall traces, refer to Save and Recall, page 79.
To make a match measurement, follow the procedures in this chapter
in the order they are presented.
Determine the Power of the Component Being Tested
Use a service monitor, power meter, or spectrum analyzer to check that
the component being tested does not have power greater than +22 dBm.
CAUTION
+22 dBm max. input
Do not apply RF power to Antenna Test Port.
Exceeding the maximum input will damage the
Site Analyzer.
