Application FEC (App. FEC)
Application data status based on the FEC
"OK"
Application data correct
"NOK"
Application data not valid, no bits corrected
<x>
Number of corrected bits in the application data
Slot Occupancy (S.Occu [%])
The percentage of the available bits in the slot that contain burst data, calculated as:
<bits_burst> / 1968.75 bits *100 %
Bit error rate (BER) before FEC
Bit error rate (BER) before forward error correction (FEC). The
are used to detect the bit errors.
Calculated as:
<bits_ok> / <bits_error>
To reset the BER value use the
function.
Remote command:
Valid Bursts (Valid B.)
Number of received bursts that passed the cyclic redundancy check (CRC) and are
thus considered valid.
function.
Failed Bursts (Failed B.)
Number of received bursts that did not pass the cyclic redundancy check (CRC) and
are thus considered invalid.
function.
Sync. Sequence (Sync. [us])
Position of the synchronization sequence within the burst in
μ
s.
Overload
Indicates a power overload at any of the input connectors, which may account for inac-
curate results. If an overload occurs, an error message is also displayed in the mea-
surement information in all GBAS / SCAT-I views.
"OK"
No overload
"RF Ovld"
Input signal too high
"IF Ovld"
IF signal too high
"ADC Ovld"
ADC input signal too high
