1xEV-DO Pilot Channel Analysis
The Agilent E6474A system measures 1xEV-DO, cdma2000, IS-95 and J-STD-008 CDMA
pilot channels. These measurements are independent of network parameter settings. The
system executes four different types of CDMA pilot channel measurements (listed below).
Any or all of them can be executed simultaneously.
The Agilent “C” revision receiver can measure both 1xEV-DO and cdma2000 carriers with
one receiver by opening two Pilot Analyzer views and properly configuring the
measurement Mode.
Measurement types
 All pilots: The system measures the power, both Ec and Ec/Io, of all 512 pilot
channels. The results are displayed as a trace with one point for each of the 512 PN
offsets.
 Top N: The system measures all of the pilots in the network and returns the ‘N’
strongest pilot channels received, where ‘N’ is a user definable integer from 1 to 20.
The results are displayed in bar graph format.
 Zoomed pilots: The user sets the center and span in terms of chips (or PN offsets).
The results are displayed as a trace.
 User list: The user manually inputs a list of up to 40 PN offsets to be measured. The
measurements are displayed in bar graph format – up to 20 bars. If more than 20
channels are in the list, all channels will be measured and recorded, but only 20 will
be displayed.
