The Agilent VQT Portable Analyzer is a rugged, portable, and powerful PC running Windows NT. Standard features include two PCMCIA card slots, a CD-RW drive, a high-density floppy drive, and speakers. Using the VQT Portable Analyzer, you can test voice-over-packet (VoP) quality, gather and compare end-to end voice quality information, augment other traditional telephony test suites (such as TIMS), and access and run VQT tests from a remote location. You can also measure fundamental voice quality metrics such as clarity, delay, echo, and signal loss; evaluate VoP operations such as voice activity detection (VAD) and DTMF tone detection; and use tone and noise generators and wave file playback and record test tools. Implement a client/server architecture for stand-alone or remote test systems, and perform voice quality testing across most TCP/IP networks using multiple hardware platforms
Distributed VQT software allows client software for PC control of remote VQT Servers
