Signal levels
of real live
data from a
gigabit switch
The signal level screen is a powerful tool. It is a live signal at-
tenuation display. If the level is below the DATA MIN line, you may
experience faulty transmissions. If the signal is well above the DATA
MIN line, you have plenty of "headroom".

The two examples shown shows off the differences between gigabit
devices and 10MB and 100MB devices. With a gigabit device it is possible
to view real live data on all 4 pairs whereas a 10MB and 100MB can
only transmit on 1 pair. A gigabit device is a full duplex device that uses
2 pairs to transmit and 2 pairs to receive data...and it can be tricked
into displaying the data on the 2 receiving pairs.... therefore making it
a perfect device to get a full view of all 4 pairs of the cable.
