Introduction
The DA280 is a handheld tester, which provides a quick
and accurate evaluation of parameters on the ADSL
/ADSL2/ADSL2+. These parameters include max bit rate,
noise margin, power attenuation, and much more. With a four
hour rechargeable lithium battery and many applied functions,
it is the ideal tester for initial installations, maintenance, and
troubleshooting.
