Instrument Information

Select the

Traffic Plus

icon as shown in the

image to the right to perform a Traffic Control

Plus measurement using the 180 DSP.

The Traffic 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.

Traffic Control Plus
