Preparing to Make W-CDMA or W-CDMA (with HSDPA) Over the Air Measurements
An important consideration when making W-CDMA or W-CDMA (with HSDPA) over the air measurements is your location relative to the base station. There must be no obstructions between your location and the base station antennas. Also, the GPS antenna must be able to "see" the satellites to obtain lock. You must know the channel or frequency and the Channel Standard of the W-CDMA or W-CDMA (with HSDPA) signal to be analyzed.
Once you have connected the proper antenna and filter to the test set, chosen a stationary location, and verified that you have a clear view of the base station antennas, you can perform W-CDMA or W-CDMA (with HSDPA) over the air measurements.
If this is the first W-CDMA or W-CDMA (with HSDPA) over the air measurement for this base station, you must find a location that meets the criteria for making a valid measurement. Your location must have a dominant pilot and very low multipath power. If you have made W-CDMA or W-CDMA (with HSDPA) over the air measurements at this location before and know it provides valid measurements, skip to "Performing a Basic Over the Air Measurement"
