This read-only screen displays the following Rx operating parameters:
Item
Description
Fc
Displays the received carrier frequency offset in Hz. The range is the same as the acquisition
range of the modem – 60 kHz.
RSL
Displays the signal level of the received carrier in dBm. The range supported is (+)15–(-60)
dBm.
BERT
Displays 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.
Buf
Displays the buffer fill status in a percentage format.
Eb/No
Displays the estimated Eb/No of the received carrier. The range is threshold to 20 dB Eb/No.
EVM
Displays the Error Vector Magnitude based on the demodulator’s estimate of the carrier to
noise.ratio
