Manual Troubleshooting Procedures (Step 4)
If you are not sure a problem exists, you should attempt to duplicate the
suspected problem. This is especially important if the Test Set is being
used in a new application where misapplication, or incorrect operation
of the Test Set may be involved.
An Agilent 8924C Mobile Station Test Set combined with an Agilent
83236B Cellular Adapter can be used to simulate a high performance
CDMA base station and may be useful in attempting to duplicate the
problem.
Refer to following table to determine which diagnostic tests,
performance tests, and periodic self calibration adjustments apply to an
assembly. Downloading calibration data is discussed in Chapter 7 ,
“Periodic Adjustments,” on page 157.
