being tested.

 

3

Also in the main menu, enter the Base Station PN Offset.

 

4

that are active.

Notes

The Tune Freq displayed at the bottom of the CODE DOMAIN ANALYZER screen

 

does not indicate the true tuned frequency of the Test System. The tuned

 

frequency is calculated from your entry for Base Station Channel and can be

 

viewed at the bottom of the main menu screen. Do not make changes to the Tune

 

Freq setting of the CODE DOMAIN ANALYZER screen.

 

If you are planning to test Code Domain Timing or Code Domain Phase, you can

 

use the Measurement field to activate them without having to return to the main

 

menu.

 

Refer to the HP 83203B or 83205A Cellular Adapter User’s Guide for more

 

details on the use of the Code Domain Power screen.
