4.3.6 Monitor Menu Options and Parameters
EVENTS Displays a history of events recorded in the event buffer.
A maximum of 100 events may be stored in the buffer.
Upon receipt of the 101
st
event, the first received event
is automatically deleted, and so on, maintaining the
maximum 100 events.
ERASE EVENTS.. PRESS CLEAR Allows the user to clear the contents of the Event Buffer
by pressing <CLEAR> on the keypad.
INPUT LVL (dBm) Displays the estimated receive signal level as seen by
the Demodulator.
EBNO (dB) Displays the estimated E
b
/N
o
as seen by the
demodulator.
REMOTE EB/NO Remote EB/NO displayed when modem is configured for
Radyne AUPC.
RAW BER Displays the estimated channel error rate (before
decoding) measured by the modem.
CORRECTED BER The CBER display shows an estimated corrected bit
error rate of the modem. Depending on the symbol rate
the modem is running, the high-end performance scale
of this display will vary (10 E
-9
, 10
-10
or 10
-11
). At some
symbol rates, a better than scale reading will appear as
0.0 x 10
-00
. At other symbol rates, it will appear as E**. In
either case, they both mean performance is better than
the scale upper limit.
BIT ERRORS Displays the current error count from the Viterbi
Decoder.
FREQ OFFSET Displays the received carrier frequency offset as
measured by the modem.
TOTAL PACKETS Displays the total number of Ethernet packets received
from the satellite (Only visible when Ethernet is
selected as the interface type).
ERROR PACKETS Displays the number of error Ethernet packets received
from the satellite (Only visible when Ethernet is
selected as the interface type).
PKT ERROR RATE Displays the satellite Packet Error Rate (Only visible
when Ethernet is selected as the interface type).
PKT STATS RESET Allows the user to reset the Ethernet packet statistics by
pressing <Enter> (Only visible when Ethernet is
selected as the interface type).
LINK STATUS (menu) (the following sub-menus only display when
Ethernet is selected as the interface type)
