Agilent launches PXT wireless test set for testing voice quality on voice-over-LTE

Telecom Lead Asia: Test and measurement major Agilent
Technologies has launched Agilent PXT wireless communications test set for
testing voice quality on Voice-over-LTE (VoLTE) 4G phones with the Bruel &
Kjaer PULSE Audio Analyzer and Head and Torso Simulator (HATS).

Transporting voice over a packet-based LTE cellular
infrastructure poses challenges that make voice-quality testing essential.

The performance of our measurement systems relies
heavily on the capability of the test equipment we support, so we are pleased
to announce that, in working closely with Agilent, we now offer this complete
VoLTE audio quality test solution to our customers,” said Lars B. Nielsen,
market manager for Telecom & Audio within Bruel & Kjaer.

The Agilent and Brüel & Kjær solution combines
standards-based test methods with real-world base station emulation, RF test
and functional test to ensure that VoLTE phones will meet user’s expectations.

We are delighted that Brüel & Kjær chose to
integrate the Agilent PXT wireless communications test set with their PULSE
Audio Analyzer and HATS system,” said Andy Botka, vice president and general
manager of Agilent’s Microwave and Communications Division.

The Brüel & Kjær PULSE Audio Analyzer and HATS system
support testing based on commonly used international standards such as ITU-T
P.862 PESQ, 3GPP2 and 3GPP audio test specifications.

The Agilent PXT wireless communication test set
represents a significant breakthrough in testing LTE user equipment.

It incorporates flexible base station/network emulation,
RF parametric and functional tests into one integrated unit and extends
Agilent’s unmatched portfolio of LTE test solutions for development and

Used with Agilent’s E6966A IMS-SIP Network Emulator
Software, the Agilent PXT enables VoLTE phones to make end-to-end voice and
video calls using a wide range of industry standard codecs.
