Measurement Data

The DOCSIS GRAPH display contains all of the DOCSIS Ranging results. This measurement data is captured and continuously updated during the DOCSIS test process. The DOCSIS GRAPH is designed to display all bonded channel results for a DOCSIS 3.0 connection in a MINISCAN style display. To view the GRAPH press the VIEW softkey, use the arrow keys to select Graph View, and press ENTER.

NOTE:
Upstream and Downstream ranging results are displayed on separate graphs. To change the view setting between upstream and downstream data, select the appropriate setting from the VIEW menu.

When in the DOWNSTREAM TABLE view, the lower section will contain the following data: Channel Number, Frequency, Level, MER, Pre-BER and Post-BER. In both views, the LEFT and RIGHT keys will change the current selection.
