CDMA Measurements - Screens and Control Fields

Control Fields for CDMA Measurements

Phse

This field displays the results of the code domain phase measurement. This field is displayed on the CODE DOM screen when the Measurement field is set to Phase.

For more information about the code domain phase measurement see “Code Domain Phase (Phse)” on page 141.

Screens on which this field is present

CODE DOM (Code Domain Analyzer, IS-95 only)

PN Incrment

This value is used to calculate the PN offset for the system. This field is displayed for EVM or Rho measurements when the Find PN field is set to Auto.

If you know the PN increment for the system you are testing, you can enter it in this field (this speeds the PN offset calculation). Enter 1 in this field if the PN increment is unknown.

PN Offset

 

This field is displayed for EVM or Rho measurements when the

 

Find PN field is set to Manual.

 

Use this field to enter the PN sequence offset index for your base

 

station. Each whole offset is equal to 64 chips (= 52.08 ∝ s). Fractional

 

values are rounded off, and can be entered, in increments of 0.015625

 

(1 chip). Once entered, this value is shared by all CDMA screens.

 

This value is used by the analyzer when the Even Sec In field on the

 

CDMA GENERATOR screen is set to Enable.

 

If the PN offset is unknown, the Test Set can calculate the PN offset

 

using the PN increment. See “PN Incrment” on page 165

 

When the Even Sec In field is set to Not, changes to the PN Offset

NOTE

 

field have no effect on the analyzer.
