Table 1 MDB1000 Signal Strength FOMs
SIGNAL QUALITY
These 5 LEDs have two interpretations, depending on the state of the EUM3006 if the
MODEM LED is on.
1. A rotating pattern of LEDs shows that the EUM3006 is in Auto CCU Discovery mode.
2. When a CCU has been found, the Signal Quality LEDs indicate the figure of merit for
a blend of quality indicators, including the carrier phase error and the signal to noise
ratios for each antenna pattern. The FOM is a value between 0 and 5 and is much
more qualitative that the signal strength.
Table 2 shows the meanings of each of the
LED values. LED 0 means that there are no LEDs lit.
