OMNISCANNER
Bandwidth is a measure of the usable frequency range of the link under test.
For most networks, this is the highest frequency at which the signal can easily be
distinguished from background noise. Depending on the selected Autotest, the
worst pair to pair ACR is typically 3 dB.
In the ACR screen, the Bandwidth is displayed at the top of the screen.
The pair combinations are located in the column on the left side, followed by
the measured ACR, the ACR margin/limit, and the frequency. The result for each
pair combination is tagged with a PASS or FAIL indicator.
Press or to toggle between ACR results for OMNIScanner and
OMNIRemote.
Press (Graph) to view the graph for the currently highlighted pair
combination. The values for Attenuation and NEXT are shown at the top of the
screen. Attenuation and NEXT graphs are displayed for the frequency indicated by
the cursor position.
