CDMA Measurements
• Relative code domain power displays the power in each of the 64
Walsh channels, relative to the pilot’s power. (Pilot power is
approximately two-thirds of the total power.) The 64 Walsh codes (0
through 63) are represented by a vertical bar on the analyzer’s
display. To measure relative code domain power the Ch pwr unit
field on the CD Setup menu must be set to Rel (see Figure 5-6). Use
the Marker controls to move the marker to the Walsh channel (Walsh
Chan) you want to measure (see Figure 5-7 on page 140).
