Node: VAR
(1.3.6.1.4.1.32108.2.2.3.3.1.3)
Parameters:
INTEGER, only viewing, list
Description:
View the value of video/audio ratio for analog channel. The value is expressed in
(dB * 10). For digital channels the value is always set to
0.
Example: VAR.2
85.
The video/audio ratio of the second channel is 8.5 dB.
Name:

Node: CNR
(1.3.6.1.4.1.32108.2.2.3.3.1.4)
Parameters:
INTEGER, viewing only, list
Description:
View the value of signal/noise ratio for analog channel. The value is expressed in
(dB * 10). For digital channels the value is always set to
0.
Example: CNR.2
432.
The signal/noise ratio of the second channel is 43.2 dB.
Name:

Parameters:
INTEGER, viewing only, list
Description:
View MER value for digital channel. The MER value is expressed in (db * 10). If
synchronization with the channel is not achieved, the
0
value is indicated. For
analog channels the value is always set to
0.
Example: MER.3
322.
MER value of the third channel is 32.2 dB.
Name:

Node: preBER
(1.3.6.1.4.1.32108.2.2.3.3.1.6)
Parameters:
INTEGER, viewing only, list
Description:
View preBER value for digital channel. The value is expressed as (preBER *
10^10). If synchronization with the channel is not achieved,
2^32-1
is indicated.
For analog channels the value is always set to
0.
Example: preBER.3
11.
The preBER value of the third channel is 1.1E-9.
