The AQ2200-201 is an interface module for AQ2200 series longwave/shortwave
large-diameter sensor heads. When an AQ2200 series longwave/shortwave
large-diameter sensor head is connected and the AQ2200-201 is installed
in AQ2200 Series
frame controllers,
the AQ2200-201 allows optical power to be measured at highspeed and
with high accuracy.
