To view data for a single code layer

This task builds on the previous task to show you how to view
code-domain power for a single code layer. Single code-layer displays are
useful if the composite display does not accurately identify which layer a
channel resides in. This can happen under these conditions:
l
A time slot contains power control.
l
A time slot contains excessive noise.
l
Spreading codes are not allocated correctly (layers are transmitted on top of one
another).

Perform the previous task.

Display code-domain power for the 60 ksym/s layer in trace B:

Measurement Data
You can display code-domain power for all layers simultaneously (using
composite code-domain power) or you can display code-domain power for
a single code layer.
Like composite code-domain power, the single code-layer display shows all
active channels. However, the only channels that are colored are those in
the selected layer (using the same color as that used in the composite
display). Active channels in other code layers are not colored.
This example shows four active channels in the 60 ksym/s code layer:
channels 32 through 35. These channels are colored. Other channels, such
as channels 16 through 21 also contain power; however, these channels are
not colored since the power is not in the 60 ksym/s code layer.
