The Agilent Technologies 8935 Series E6381A
TDMA base station test set is a full-featured, onebox test set designed to meet the needs of installation teams, service providers, and network equipment manufacturers.
Building on the success of our previous generations of base station test equipment, the E6381A
heavily incorporates feedback from PCS and
Cellular users. For example, the E6381A utilizes a
large, bright, easy-to-read, 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 “rugged” design includes a reliable membrane
keypad, a gasketed display, and filtered
airflow to resist dirt and moisture. The unit’s
enclosure provides for stand up operation, and
helps protect itself from bumps and shocks.
The E6381A incorporates a user-friendly interface
with one-key measurement execution. This inter-
face, coupled with the test set’s fast measurement
speed and automated software for Ericsson,
Lucent, and Nortel 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 PC memory card. Additionally, new features
and capabilities can be added to the E6381A without returning the unit to a service center. The test
set’s firmware is user upgradeable via a PC card to
Flash Memory.
To complete the TDMA parametric test solution,
Agilent also offers a new TDMA technician training
program to provide install teams and service
providers with a comprehensive understanding of
base station test.
