Check that all applicable tuners
are powered ON and locked to
an antenna signal, and then
check the signal-to-noise ratio,
FEC errors, and input bitrates
for each tuner.
Check that the tuner
channels are valid. If
necessary, reconfigure the
tuner channels as described
in this document.

Note: In the GUI, the Tuner Information
display provides data for each of the
OAT100R tuners. If using the command
line interface, you will be able to access
one tuner’s information at a time.
Tuner input
data OK?
Access the OAT100R Tuner
Information display (via GUI
or command line).
Note: For each tuner, the signal-to-noise
ratio should be greater than 18, there
should be zero (0) FEC errors, and the
input bitrates should equal 19.4 Mbps.
For example:
• Check the antenna cabling. Ensure that each cable is good and
that connections are secure both at the antenna distribution center
and at the OAT100R. Fix and verify as necessary.
• Ensure the antenna is pointed so as to achieve the best signal
quality.
• Ensure the signal level at each OAT100R RF input is balanced
within the recommended range (see OAT100R Setup Information).
• If applicable, check that the amplifier/splitter is operating properly.
Verify that the antenna(s)
are installed and pointed
properly.
