Code Domain Tests
This test performs a suite of CDMA transmitter tests on the selected BBA. Unlike the
Pilot Only test, in this test one or more traffic channels (channel elements) are turned
on.
When you are sending commands to the MSC, you must enter the number of channel
elements (CEs) to test on the Base Station Configuration Menu screen. Call processing
must be deactivated by sending the Inhibit cp command in the BTS Laptop Utility
program Switch Terminal window or by some other means, before testing begins. For
information on enabling automated control, see “Base Station Configuration” on page
41.
The following measurements are performed:
• Time offset
• Frequency error
• Carrier feedthrough
• Code domain tests on traffic channels (if CEs are configured)
TX Walsh code power
Estimated rho
Walsh code timing
Walsh code phase
