5.3.4 A TTENUATION
The Attenuation function measures signal loss in a cable as a function of
frequency. OMNIRemote generates and injects a signal at the far end of the cable.
OMNIScanner measures the signal at the other end of the cable to determine
cable loss.
In the ATTENUATION screen, the worst case margin for all pairs is shown at
the top of the screen.
The pairs are displayed in the column on the left side, followed by the
Attenuation in decibels (dB), the Attenuation margin/limit values, and the
frequency. The result for each pair is tagged with a PASS or FAIL
indicator.
Press (Graph) to display the Attenuation graph for the highlighted pair.
