To View Data For A Single Code Channel - Agilent Technologies 89410A Operator's Manual

To view data for a single code channel

This task builds on the previous task to show you how to view the vector
diagram for individual channels. The power varies in each channel. The
task turns normalization off so you can see the vector diagram change size
when you change channels.

All time-domain measurement data (except composite time domain) and
the symbol table show results for a single channel in a single code layer
(you use the [

data and the symbol table). By default, the analyzer uses channel 0 in
slowest code layer. This procedure shows you two ways to select a
different channel and layer—using the [
