Criteria for Making Valid 1xEV-DO Over Air Measurements
1xEV-DO Analyzer and Over Air
Test
The default measurement limits for pilot dominance and multipath power are set to
give “fair” measurement quality. If these limits are met, the pilot dominance and
multipath power values will be displayed in green. When the pilot dominance and
multipath power parameters are outside the acceptable limits, the parameters will
turn red. If this occurs, you must move to a different location that meets the “fair”
criteria defined above.
In general, you should always use a preselector filter for the band of interest to
prevent strong signals from swamping out the signal of interest. Agilent offers these
preselectors and antennas:
• Option 810—Cellular downlink band preselector and antenna
• Option 811—PCS downlink band preselector and antenna
• Option 812—Korean PCS downlink band preselector and antenna
