Time offset (Tm Ofs) and frequency error (Freq Err) are always displayed when any code domain measurement is made. Carrier feedthrough (CarFT) is also displayed except when fast power is measured.

Code Domain Power, IS-2000

The code domain power displays the power in each of the 128 Walsh channels, relative to the total power inside a 1.23 MHz bandwidth centered at the tune frequency. The 128 Walsh channels (0 through 127) are represented by a vertical bar on the analyzer’s display. Use the Marker controls to move the marker to the channel you want to measure. Reading the Code Domain Power in IS-2000 mode is slightly different than in IS-95 only mode. Figure 5-13illustrates some of the important parameters. Note that Chan Num is now comprised of two values: the sumplemental channel (20 in Figure 5-13) and the Walsh channel ((52) in Figure 5-13).
