(6) Trace route
It is used to determine the path of the IP packet access target.
Note: Trace route testing results only for reference, for accurate test route tracking, use a professional Ethernet tester.
(7) Link monitor
This app is used to see if an IP address is occupied by other network devices. This will avoid new address conflicts.
6.2 RJ45 cable TDR test
Connect cable to tester’s LAN port, click icon “ ” to enter app.
Single test: Test cable status, length and attenuation.
Repeat test: Continue to test cable status, length and attenuation.
Status: After link-up, the screen displays “online”, or for an open circuit, the screen displays “open circuit”, if the cable pair has a short
circuit, the screen displays “short circuit”.
Length: The max test length is 180 meters, when the cable is open circuit or short circuit, can test the cable length, if screen display
“online”, the testing result would not be accurate.
Cable quality test: Green is good quality cable, Yellow is poor quality cable, Red is water damaged cable, the attenuation value will be
displayed when a cable is over 10 meters.
Advanced Test: Test cable pair status, length, attenuation, reflectivity, impedance, skew and other parameters.
Attenuation reflectivity: After link-up, if the reflectivity value is 0, it is the best quality communication
Impedance: After link-up, if the impedance value is 100 Ω, it is the best quality communication, the range is generally in 85-135 Ω
Skew: After 1000M link up, if the skew value is 0ns, it is the best quality communication, if over 50ns, it will cause a Bit Error Rate in the
transmission.
Click “Help”, check the instruction of all parameters.
