Permits the user to view the received carrier frequency offset in Hz. The range
is the same as the acquisition range of the modem, 60 kHz.
Permits the user to view the signal level of the received carrier in dBm. The
range supported is +15 to –60 dBm.
Permits the user to view the measured BER. This requires that the modem be
set to Test mode for Rx. If a Fireberd is supplying a data pattern, only the Test
mode for the Rx needs to be turned on. The Fireberd data pattern and the
modems data pattern must match to work properly.
Permits the user to view the buffer fill status in a percentage format.
Permits the user to view the estimated Eb/No of the received carrier. The range
is threshold to 20 dB Eb/No.
Permits the user to view the estimated BER based on the demodulator's
measurement of the carrier to noise.
The difference between BER and BERT is: BER is estimated in the
demodulator, BERT is measured when the test mode is turned on.
Config
Permits the user to view the stored statistics. The statistics are limited to
minimum, average and maximum Eb/No.
Permits the user to clear all stored statistics.
Permits the user to set the interval that the statistics are stored. This ranges
from 10 minutes to 90 minutes in 10 minute steps. The function can also be
disabled.
