Check the current stored signal strength
(absolute transmission) by entering the
17
command:
#MR 5
Store the current signal strength (optimum
alignment) to the transmission reference by
entering the following command:
18
#MW 2 <absolute transmission>
Use the <absolute transmission> value
received in the step above.
Check that the absolute transmission is as expected (indicated in the graph below). The
obtained absolute transmission can vary somewhat from detector to detector. If the signal is
significantly lower than the suggested values, this is an indication that the fine alignment
needs to be improved, the RX is poorly aligned or the lenses are dirty. The RX is usually well
enough aligned during the Coarse alignment, but this can also be a reason for too low signal.
