Balance Test
The VF Longitudinal Balance test allows you to check that the pair balance
is sufficient to mitigate common-mode noise. The test is a measurement of
how much the T/A leg is like the R/B leg in electrical characteristics,
measured by how much noise the line can mitigate (in dB). It is an overall
health indicator and a quick way to tell if the line is in good condition. The
better the longitudinal balance of the cable pair, the higher the dB reading.
