 SPECIFICATION
DETAILS
It is important to understand the extent to which each
and every Down converter is tested before leaving the
factory. A test is performed on every DC for most of
the items, such as noise, gain, gain flatness etc.,
and so on down the list. Besides these routine production
tests, 150 pieces out of every 1,000 produced are tested
fully to the MIL-STD-1050 LEVEL which determines that
statistical acceptance standards for the routine production
are of a sufficiently high level.
