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.

following data: Frequency, Bandwidth, Encoding Type, Modulation, Level
and Headroom. 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
