Locking state of each channel. Displays “Locked” (green) when the PLL
and the Bit Synchronization loops are locked, “Unlocked” (red)
otherwise.
IF LEVEL
IF carrier level. Expressed in dBm.
CARRIER OFFSET
Offset from the specified IF carrier frequency (real frequency – expected
frequency). Expressed in Hz.
Eb/N0
Energy per bit in a 1-Hz noise bandwith. Expressed in dB.
Status of the combining:
COMBINING STATUS
Locked (green), Check (green), Acquisition (amber), 1-channel (green),
Unlocked (red), N/A (gray).
RELATIVE GAINS
Comining weights, expressed in %. In Best Channel mode one weights is
equal to 0, % the other one equals 100 %. The same goes when the unit is
in Single channel state.
EB/N0
Energy per bit in a 1-Hz noise bandwith of the combining unit output.
Expressed in dB.
COMBINING GAINS
Gain in energy per bit in a 1-Hz noise bandwith of the combining unit
output. Expressed in dB.
