Hitron CODA-551x User’s Guide
Upstream Overview
NOTE: The upstream signal is the signal transmitted from the CODA-551x.
Port ID This displays the ID number of the upstream
connection’s port.
Frequency (Hz) This displays the actual frequency in Hertz (Hz) of each
upstream data channel to which the CODA-551x is
connected.
Modulation This displays the type of modulation that each upstream
channel uses.
Signal Strength
(dBmV)
This displays the power of the signal of each upstream
data channel to which the CODA-551x is connected, in
dBmV (decibels above/below 1 millivolt).
Channel ID This displays the ID number of each channel on which
the upstream signal is transmitted.
Bandwidth This displays the maximum available bandwidth on the
relevant channel.
OFDM/OFDMA Overview
NOTE: This section of the GUI provides data about upstream channels.
Channel Index This displays the index number of the OFDM/OFDMA
channel.
State This displays whether or not the relevant channel is
currently in use, or not.
ENABLED displays when the channel is in use.
DISABLED displays when the channel is not in
use.
Lin Digital Att. This displays the digital attenuation, or signal loss, of
the transmission medium on which the channel’s signal
is carried, in decibels (dB).
Digital Att. This displays the measured digital attenuation of the
channel’s signal, in decibels (dB). Digital attenuation is
affected by the frequency of the signal; a higher-
frequency signal will suffer more attenuation than a
lower-frequency signal.
