CDMA Over Air
NOTE The test set does not record data for post-processing. It provides a snapshot of
CDMA base station transmit parameters at that location.
NOTE During a CDMA over air measurement, a yellow triangle symbol may temporarily
appear beside “GPS” in the lower right. The yellow triangle indicates that the test set
is re-synching with the GPS even second pulse. Once the test set is synchronized, a
green dot appears in place of the triangle. If the GPS is unavailable, a red X appears.
If this happens, you must choose another reference.
Displaying Location Information Using GPS
If you are making CDMA over air measurements at a location you previously
established as valid, Agilent recommends using GPS to verify that you are at the
location from which you previously measured.
If you are making CDMA over air measurements from a new location, once you
validate that the location provides a dominant pilot and low multipath power,
Agilent recommends that you record the latitude and longitude coordinates of this
location using GPS. Later measurements should be made from this precise location
to provide performance trends.
For additional information on the GPS Data function, refer to “Displaying GPS
Location Data” on page 462.
