The Agilent Technologies 8935 Series
E6380A AMPS/CDMA Cellular/PCS
base station test set is the next generation in CDMA base station test
equipment. The E6380A is a full
featured, one-box test set designed
to meet the needs of installation
teams, service providers, and network
equipment manufacturers.
Building on the success of our third
generation of base station test
equipment, the new test set heavily
incorporates feedback from PCS and
Cellular users. For example, the
E6380A utilizes a large, bright, easy-toread, electroluminescent display. A
convenient connector section on the
side of the test set allows unobtrusive,
out-of-the-way hook up, as well as
protects the connectors from damage.
A suitcase form factor provides better
portability.
The new “rugged design” includes a
reliable membrane keypad, a gasketed
display, and filtered airf low to resist
dirt and moisture. The unit’s enclosure
provides for stand up operation, and
helps protect itself from bumps and
shocks.
More importantly, the E6380A incorporates a user-friendly interface with
one-key measurement execution. This
interface, coupled with test set’s fast
measurement speed and automated
software for LGIC, Lucent, Nortel,
and Samsung base stations, results
in less off-line time and improved
system performance. Errors due to
test variability are reduced, and
measurement data can be output to
a printer or to the PCMCIA memory
card. Additionally, new features and
capabilities can be added to the
E6380A without returning the unit
to a service center. The test set’s
firmware is user upgradeable via a
PCMCIA card to Flash Memory.
To complete the CDMA parametric test
solution, Agilent also offers a technician training program to provide
install teams and service providers
with a comprehensive understanding
of base station test.
