Select the Trafc Plus icon as shown in the
image to the right to perform a Trafc Control
Plus measurement using the 180 DSP.
The Trafc Control Plus spectrum menu
provides a real time view of the return band.
This menu has 100% coverage, so even the
shortest cable modem burst can be seen.
It will also show ingress even under a busy
upstream.
In a typical HFC plant the RF spectrum is
divided into two main bands, the forward band and the return band.
