CDMA Measurements

IQ Constellation Diagram, IS-2000 only

If you have the IS-2000 option installed, you will be able to select the I/Q PLOT screen from the set of available measurements.

Figure 5-16 IQ Constellation Diagram

The I/Q Constellation Diagram screen graphically shows I/Q decision points. This is a useful troubleshooting tool when investigating Rho problems

Visual presentation helps identify IQ errors. Figure 5-16shows no errors. However, the 4 point groupings could be skewed away from perfect square or offset indicating a phase error. This will result in interference from I to Q and from Q to I. Phase errors can result from crosstalk between I and Q in the base station baseband processing section, misaligned LOs or intermodulation between Walsh codes.

PN Offset Search

There are two ways to provide your Base Station’s PN Offset value to the Test Set:

•Enter the value directly. See “PN Offset” on page 165

•Have the Test Set determine the value from the received signals. See “PN Incrment” on page 165
