Cabling is connected to a device at the far end, such as a
television, CATV service, VCR, DVD player, satellite dish,
or antenna.
The signal level graph indicates the strength of the
signal. Passive (non-amplifying) devices, such as satellite
dishes and antennas, usually produce low-level signals in
the cross-hatched area at the left side of the graph.
Active devices, such as CATV service or a DVD player,
produce levels beyond the cross-hatched area. The
example above shows a VCR’s signal level.
