Using the Code Domain Analyzer

Using the Code Domain Analyzer

The code domain analyzer has two display modes, selected in the Inst Config screen:

•IS-95– corresponding to the standard that specifies 64 channels in the Hadamard (consecutive integer) ordering. This code domain view graphically displays the power, phase, and timing of the CDMA signal’s 64 Walsh channels.

•IS-2000– corresponding to the standard that specifies 128 Walsh codes. This code domain view graphically displays power, fast power, power & noise and complex power of the CDMA signal’s 128 Walsh codes.

Selecting the Code Domain Analyzer’s Controls Menus

Several levels of menus are used to access the various controls associated with the code domain analyzer. “Control Fields for CDMA Measurements” on page 150 provides a description for each field on the code domain analyzer’s menus. See “CDMA Measurements” on page 131 and the Agilent Technologies 8935 CDMA Base Station Tests Applications Guide for more information about code domain measurements.
