Digital Channels
When channels set up as digital channels in the Channel Table
are measured, the display is automatically configured for digital
measurements. These measurements are made using an average
power detector, per DOCSIS and ITU-T J.83 requirements, over
the appropriate bandwidth.

Bar Graph – Since no video carrier or audio carriers are present,
the digital channel bar graph occupies the space of all three. Only
the digital channel’s level and the adjacent channel level are
graphed.
