XG2128
E1 BER tester
XG2128 E1 BER tester is a small and
mini-functional handheld E1 line test instrument which is to do BER test, frame
analysis, time slot analysis, signaling test, sign analysis, alarm analysis and
so on. It is not only durable and easy to use, but also has high
performance–to-providing ratio, especially for simplifies installation
and maintenance testing for faster problem resolution.
