CDMA Measurements - Screens and Control Fields

Control Fields for CDMA Measurements

I Power Level

This IS-2000 Code Domain display field shows the power of the currently selected I (in the top bar graph) Walsh code.

Screens on which this field is present

COD DOM (Code Domain Analyzer, IS-2000 only): Complex Power measurement.

Marker Lvl

This display field shows the level of the channel or Walsh order at the current marker location (IS-2000 only) relative to the 0 dB reference level shown in Pwr Ref in the Marker control view. The location of the top of the channel relative to the reference level is determined by the Pwr Scale setting, also in the Marker control view.

The value for the power is calculated by averaging the total power over a 1.23 MHz bandwidth centered around the Tune Freq setting.

COD DOM (Code Domain Analyzer, IS-2000 only)

Marker Pos

This Code Domain field sets the index (starting at the left side of the bar graph) for the current marker location (IS-2000 only).

Screens on which this field is present

COD DOM (Code Domain Analyzer, IS-2000 only): Marker Controls menu.

Meas Intvl or Meas Int

This field determines the length of the data block. The data block is a time record over which correlated measurements are computed. As the interval is increased, measurement time is increased. Increasing the interval gives more accurate measurement results, particularly with frequency error and phase error measurements.

This field is displayed on the CDMA ANALYZER screen when a rho or EVM measurement is selected. It is also displayed on the CODE DOM (Code Domain Analyzer) controls menu.
