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 making a match measurement, be sure to have a Bird Calibration Combi-
nation (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 provides step by
step instructions. In addition, this chapter describes how to set and move mark-
ers. For information and instructions to save and recall traces, refer to Saving
and Recalling Traces, page 56.
To make a match measurement, follow the procedures in this chapter in the
order they are presented.
