Interpreting the Display
The CDMA Tx Analyzer screen is divided into two sections:
The trace display contains a code domain power display. In this display 128 Walsh codes are shown in bit-reversed order to represent the combined code channels for the varying data rate traffic channels. The Y-axis labels display the relative power (dB) or absolute power (dBm), threshold level, and dB/division. The X-axis labels display active channel numbers. Active channel Walsh code numbers shown on the display include:
- The trace display - that is, the graphic bar chart taking up most of the screen
- The metrics display - that is, a table of values at the bottom of the screen
The metrics display shows 12 measurement parameters displayed below the trace display in three columns and four rows-each with a value and units. For more information about the parameters in the metric display, refer to "Metrics Provided by the CDMA Tx Analyzer Measurement"
- Pilot (red)
- Page (green)
- Sync (blue)
- Quick page (light blue)
- IS-95 traffic (yellow)
- cdma2000 traffic (orange)
- Unknown traffic (tan)
- Noise (light gray)
The frequency indicator is at the bottom right, the time reference indicator at the bottom left. For each indicator the text indicates which reference you have chosen. A green LED indicates a locked condition, a red "X," an unlocked condition.
