Super Eagle CDMA Pilot Scanner
The Super Eagle™ is a mobile, high speed field measurement device that surveys Cellular
or PCS CDMA Pilot channel signals and reports their power profiles.
Measuring Ec/Io, total power (dBm) in the CDMA channel as well as absolute
power (dBm) profiles from each CDMA base station, the Super
Eagle generates these correlations using internal, high speed
parallel architecture in realtime. These profiles indicate the distribution
of interference and multipath components as a function of relative power
and delay.

The
system employs an eight channel internal differential GPS and gen-lock
system to synchronize the unit's clock time and track the CDMA signals.
The Super Eagle can be configured
to survey all or just specific base stations including power and signal
thresholds to reduce the overall data collection. This allows the user
to generate specific criteria for propagation analysis. With 1/2 chip
resolution, (upgradeable to 1/4 chip) the Super
Eagle can scan all 512 base stations and the associated multipaths
from each base station. The user may also upload a list of base stations
to be measured as well as a search window for base stations which is
defined as the number of chips around each base station.
The Super Eagle excels in conducting
accurate CDMA coverage studies, base station transmitter testing and
setting hand-off thresholds. The heavily parallel, expandable and high
speed time multiplexed architecture and DSP downloadable PN phases allow
capture of real-time co-channel interference, multipath analysis Received
Signal Strength Indication (RSSI).

All PN Scanners are the Same
As
you know this year, a competing hardware manufacturer has raised the
bar with a new list price for the their PN Scanner system by
$10,000 more. This is good news for Berkeley Varitronics. More importantly,
since the competition's costs more, it forces customers to address the real functional, operation and technical advantages of the Berkeley Super Eagle over other PN Scanners;
not just the 30% gap in price. The rational that the competition used
to raise their price is that their customer's demanded they include
the ability for multiple receivers to be used with PN Scanner in order
to measure comparative frequencies (different RF channels) of CDMA signals
simultaneously.
The BVS Eagle and Super Eagle scanners can scan very fast (in
under 27 milliseconds for all PN half-chip positions) and measure multiple
RF channels, without the need for added receivers. Dual RF channel measurements
are reported and displayed at a rate greater than twice per second (four
times faster than the competition with only a single channel measurement).
The extraordinary speed of measurement and BVS' agile receiver, account
for this stellar feature.
Our scanner is between four (the worst case) and seventy-five (the best
case) times faster than the competition's, so multiple frequency measurements
are possible and still faster than the competition's PN Scanner; without
additional hardware. We have some customers that appreciate this feature
when comparing their own local coverage vis-a-vis several RF channels.
It provides faster, more accurate measurements for handoff criterion
than single RF channel measurements drive studies.
BVS believes a fast PN Scanner is essential to capture and record fast
CDMA fades of correlated (the signal of choice without interference
and noise) CDMA energy. The competition can report all 512 PN points
of energy in under 2 seconds. The Super Eagle can report this energy in as little as 27 milliseconds. In other words,
the Super Eagle "takes a snap-shot"
of all base stations" rather than sequential measurements smeared
over several hundred feet of drive analysis. Also, Super Eagle's reports are not just a single
path within a 64 chip window, but include all multipaths. This
makes Super Eagle a precision Engineering
Tool; not just a "Technician's realtime signal checker. RF engineers want the best instrument available for precise measurements,
