additional information.
This field displays an integer value representing an expected power level
threshold. The purpose of this calculation is to determine the approximate power
level threshold that will cause the mobile station to send a pilot strength message
reporting that an Active pilot signal strength has lowered to a point where it
should be dropped from the Active set.
To compare the integer value in the Expected T_Add field with the pilot strength
the mobile station is currently receiving from the Test Set, refer to the
Strength" field on page 255
The Test Set will update the status of each pilot strength report in the Status
column on the CDMA MOBILE REPORTED PILOT STRENGTH screen.
HP-IB Example
"CDMA:MOBile:PARM:ETDRop?"
queries the Expected T_Drop value calculated by the Test Set.
Operating Considerations
If there is a call connected with the Soft Handoff field On and the status of both
pilot signals is Active, the mobile station should report To Drop (in the Status
field) if it detects that one of pilot's signal strength has decreased to less than
Expected T_Drop.
The value displayed in this field is calculated from the current T_Drop field and,
if Soft Slope is not 0, the Drop Intcpt field. .
