SGT-701B ADSL Tester

General
The SGT-701B ADSL Tester is a hand-held communication instrument that supports batteries as power supply, and has a large screen with Chinese display. This product is particularly applicable for the field cutover, acceptance and maintenance of ADSL equipment, and can be widely used by ADSL business operators like China Telecom, China Railcom, etc, and is the best choice of ADSL engineers and technicians.
Major Features
" Chinese menus. Large screen. Easy operation;
" Portable design. Built-in large-capacity lithium cell to allow its working time to be as long as 6 hours and longer.
" Multitask support (It is allowed to conduct a test while browsing previous records).
" Test setup is allowed. Test results can be stored or deleted. Memory remains in the event of power failure.
" As many as 7 test settings can be stored, and 100 groups of test results can be stored.
" Perfect alarm detection and indication.
" The tester can be connected to a computer via a serial port to enable storing, analysis and printing of the tested data to be carried out on the computer.
" Software can be updated online.
Major Functions
For ADSL physical layer, following items can be tested:
" Fast channel and interleave channel.
" Line parameters testing: Speed of up and down channels, line loss, noise margin, transmitting power, and use rate of channel.
" Performance analysis of line error and alarm:
- Automatic detection and display of such alarms as signal loss, frame loss, power loss and cell loss etc. at proximal end and remote end.
- Detection of fatal error frame count at proximal end and remote end;
- Detection of power loss count at proximal end and remote end;
- Detection of signal loss count at proximal end and remote end;
- Detection of interleave channel FEC forward error correcting code count at proximal end and remote end;
- Detection of fast channel FEC forward error correcting code count at proximal end and remote end;
- Detection of interleave channel CRC error frame count at proximal end and remote end;
- Detection of fast channel CRC error frame count at proximal end and remote end;
- Detection of interleave channel HEC error frame count at proximal end and remote end;
- Detection of fast channel HEC error frame count at proximal end and remote end;
- Detection of interleave channel NCD error frame count at proximal end and remote end;
- Detection of fast channel NCD error frame count at proximal end and remote end;
- Detection of interleave channel OCD error frame count at proximal end;
- Detection of fast channel OCD error frame count at proximal end.
" DMT component channel carrier wave pattern
Display the modulated bit number on each DMT component channel in form of diagram and figure.
" Display user's connection state and testing progress at real time, and present information on local equipment manufacturer and version.
For ADSL network layer, following items can be tested:
" ISP PING test
Verify the connection of user to ISP provider.
" Simulated PC logon
The instrument can be used to simulate user terminal PC logging on ISP provider to verify if ADSL user can get on the Internet. .
" LAN PING test
Verify the PC in connection failure within LAN.
" WAN PING test
Directly PING the website IP to local WAN to verify the connectivity of WAN link.
" The instrument can be used instead of ADSL MODEM to test Internet wire speed and flow available for the user.
" The instrument can carry out simulated ISP logon instead of ADSL modem to check the operating performance of users' terminal equipment.
" PPPOE dialing can know the users' dynamically distributed IP websites.
For ADSL line, following items can be tested:
" Digital multimeter (DMM) test
DMM can be used to measure AC/DC voltage, loop resistance, dielectric resistance, capacitance, etc.
" Subscriber telephone connectivity test
The separator in the instrument can be connected to an external telephone to verify the connectivity of subscriber telephone.
" Estimation of the distance of subscriber telephone wire.
