– If you are using a Qualcomm mobile, use the I and Q values from

the 13 chip delay table.

– If you are using a mobile that does not have the 1 chip offset

problem, (any mobile meeting the IS–97 specification), use the 14

chip delay table.

If the wrong I and Q values are used with the wrong

FineTxAdj parameter, system timing problems will occur.

This will cause the energy transmitted to be “smeared”

over several Walsh codes (instead of the single Walsh code

that it was assigned to), causing erratic operation. Evidence

of smearing is usually identified by Walsh channels not at

correct levels or present when not selected in the Code

Domain Power Test.
