CHAPTER 3: Cable Tests
The
SNR (Signal-to-Noise Ratio)
measurement
is displayed in dB units. A larger number is
better, indicating lower noise. A flashing SNR
reading indicates a failing Signal-to-Noise
Ratio. If the Scan-LAN 80 was unable to
measure NEXT and attenuation because
of a faulty wire map, SNR will be displayed
as “N/A.”
The bottom line of the display indicates whether
the cable will work in the selected LAN
environment.
