High Performance ADSL2+ Tester

RA4333

RA4333 - ADSL2+ Tester

ADSL2+ Tester is an easy-to-use, hand-held advanced telecommunication tester that used for the installation, maintenance and measurement of ADSL2+ service.

It supports the testing function such as parameter, error, DMM, PING that related to ADSL2+ service, user register authentication on the ADSL2+ user’s line side. It also directly enables the engineers to verify, troubleshoot and evaluate the ADSL2+ service.
