Measure Match Mode
Match measurement verifies and monitors the match
conditions in the antenna system at various frequen-
cies. The results are shown on an x-y graph. Fre-
quency 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 measure-
ment and provides step by step instructions. In addi-
tion, this chapter describes how to set and move
markers. For information and instructions to save and
recall traces, refer to Save and Recall, page 91.
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 ana-
lyzer to check that the component being tested does
not have power greater than +22 dBm.
Select the Measure Match Mode
Follow the numbered steps in Figure 3 to turn ON the
Site Analyzer and select the Measure Match mode.
CAUTION
+22 dBm max. input
Do not apply RF power to Antenna Test Port.
Exceeding the maximum input will damage the
Site Analyzer.
