Model: DA280 ADSL2+ Tester

Overview:

DA280 is a handheld ADSL2+ tester, which provides full testing and analysis of ADSL/ADSL2/ADSL2+lines accurately and fast, covering physical layer, network layer and cable physical characteristics. Givinga visual determination of the quality of ADSL lines, it is a necessary and ideal tool for installation andmaintenance of the ADSL.

Functions:

ADSL physical layer testing- Support all ADSL standards, including ANSI T1.413 Issue 2, ITU-T G.992.1 G.dmt, G.992.2G.lite, G.992.3 ADSL2, RE-ADSL2 and G.992.5 ADSL2+

- Fast and interleave signal channel BER testing- Test upstream, downstream, maximum speed and channel utilization- Test upstream and downstream noise margin, output power, and power attenuation- Bit error statistics of NEC, FEC, CRC, and HEC- Automatically detect and display LOS, LOF, LOP, LOC and LOM with the comparison between history and present data- Error seconds statistics- Display every sub-channel of Bits per Tone by the mean of graphic and number

ADSL network layer testing- Support several upper layer protocols, including RFC2684, RFC1483, RFC2516 PPPoE,RFC2364 PPPoA, DHCP and PAP/CHAP etc.- PPPoE/PPPoA/DHCP to acquire IP address and Ping testing- Fixed IP Mode Ping testing

- Ping testing that includes Ping loss testing with times and package size, Ping loopback latency testing with MAX, MIN and average- ADSL2+ modem replacement

Ethernet testing- LAN Ping testing

Cable testing- Digital Multi Meter, DMM is used to test loop resistance, insulation resistance, capacitance,AC/DC voltage and line length estimation- Tone generation

Others- Auto power-off- Sound and LED alarm indication- Data management- Software online upgrade

Features:

-Line quality pass/fail indicator: users can set their own threshold parameters of the line,by comparing the actual test results with the threshold to determine the line quality pass or fail

-Tone generation: send signal at one end, and then identify the tested line with tone generator at the other end
