Burst Level Average (Av [dBm])
Arithmetic average of the burst power level measured over the period of the synchroni-
zation and ambiguity resolution field of the burst.
If no burst was detected, the arithmetic average of the noise power is displayed.
Remote command:
LA?
on page 258
Slot Level Peak (Pk [dBm])
Highest measured power level in the slot in dBm
Carrier frequency offset (Offs. [kHz])
Offset of the measured carrier frequency from the nominal frequency
Remote command:
GBAS:FMEAS?

EVM RMS
Error vector magnitude RMS in percent.
Indicates the quality of the transmitted symbols in relation to the ideal constellation
point. The EVM normalization reference is the mean constellation power.
GBAS ID
4-character identifier of the ground station broadcasting the message. If there is more
than one message inside the burst, the first GBAS ID is displayed.
Training Sequence FEC (Train. FEC)
Training sequence status based on the FEC
"OK" Training sequence correct
"NOK"
Training sequence not valid, no bits corrected
<x> Number of corrected bits in the training sequence
Application Data (App. Dat.)
Detected message types (MT) in the burst
