Chapter 4, Description of Fields
Fields
Expected T_Add
This field is displayed only when TIA/EIA-95B is selected in the "Protocol" field
on page 346
. Refer to ANSI/TIA/EIA-95-B, 6.6.6.2.6, Set Maintenance, for
additional information.
This field displays an integer value representing a power level threshold. The Test
Set calculates this threshold based on several field settings, included in the
formula below. The purpose of this calculation is to determine the approximate
power level threshold that will cause the mobile station to add a Neighbor Set
pilot to the Candidate Set.
To compare Expected T_Add with the current value the mobile station should be
receiving, refer to the
"Expected Strength" field on page 253.
GPIB Example
“CDMA:MOBile:PARM:ETADd?“
queries the Expected T_Add value calculated by the Test Set.
Operating Considerations
The value displayed in this field is calculated by the Test Set using the following
formula (unless the
"Soft Slope" field on page 400 is set to 0):
where PS
i
is defined as E
c
/I
o
for the pilot in question.
The calculations used in determining Expected T_Add do not account for any
interfering signals the mobile station may be receiving in addition to the forward
CDMA channels from the Test Set.
If the
"Soft Slope" field on page 400 is 0, the Expected T_Add field will display the
same value as that currently entered in the T_Add field.
