Conguration Options via GUI (Cont.)
• Bitrates: If a bitrates value is shown with a
green
background, the data transmission is within
a standard operating range; if the bitrates value is shown with a
yellow
background, the
data transmission may be too slow (i.e., between 0.2 and 2 Mbps); and if the bitrates value
is shown with a
red
background, there is little to no data transmission (under 0.2 Mbps). If a
tuner is powered off, the Bitrates column will show “N/A.”
Note: The System Status screen sample on the previous page shows a typical system with RF
256-QAM output. For a system with RF 64-QAM output, the System Status will show up to four
streams. Streams 1, 2, 3, and 4 are congured by default when 64-QAM output is used, though
any four of the OAT100R tuners may be mapped to these streams (see “MUX Setup Options” on
page 35 for further information).
Tuner Information
Note: In both the System Status and Tuner Information screens, the site location, if specied
in the System Setup screen or in the command line interface Setup Menu, is identied in blue
text to the right of the screen title.
For each tuner, the Tuner Information screen identies the tuner channel number, the powered
state of the tuner, the lock status of the signal, the signal-to-noise (S/N) ratio, the number of
FEC errors, and the input bitrates.
Under standard operating conditions a powered tuner should be locked to the antenna signal;
the signal-to-noise ratio should be greater than 18; the number of FEC errors should equal “0”
(zero); and the input bitrates should equal 19.4 Mbps. If one or more tuners does not appear to
be operating normally, refer to “Receiver Reception” troubleshooting information on page 70.
