System software
The system software controls Agilent digital RF
receivers. Multiple measurements can be made
simultaneously. All measurements can be displayed
in real-time and logged to the database. The system
software option currently available:
•Option 150: code domain power and spectrum
mask software license
Receiver-based software
The receiver-based function of the Agilent E6474A
system, provided by Option 150, is comprised of
two primary elements:
• code domain power
• spectrum display with IS-97 mask
Each element has an associated control and
display window called a view. The software can
control up to four digital receivers.
CDMA code domain power
The Agilent E6474A Option 150 software measures
code domain power for cdmaOne, cdma2000 1x
and J-STD-008 signals. These measurements pro-
vide real-time insight for traffic analysis, capacity
management, and base station health. The code
domain power view is segmented into three meas-
urement types (listed below). Any or all of them
can be executed simultaneously.
Measurement types
• CDP Trace:
The system measures the relative powers of each of
the 64 or 128 Walsh codes. Data is displayed in bar
graph format with a unique color for each channel
type – pilot, paging, quick paging, sync, and traffic.
• CDP Stats:
The system displays important modulation and
traffic measurement parameters in large font text
format.
• TopN or Top 2 Pilots:
The system measures all of the pilots in the net-
work and returns the ‘N’ strongest pilot channels
received, (when E6474A Options 110, 111, 120, or
121 are included) where ‘N’ is a user-definable
integer from 1 to 20. When E6474A Option 150 is
used as a stand-alone measurement, the Top 2
pilots are measured in order to determine pilot
dominance. The results are displayed in bar graph
format.
