reduced 10 C (18 F) per minute plus or minus 1C (1.8F)
to room ambient temperature (as specified in 3.3.1). The above
procedure shall be conducted a minimum of ten times. upon
completion of the cycles the assembly shall then be removed from
the chamber and subjected to the test in 4.6.3. It shall meet the
requirements of 3.2.1.
4.6.2 ESS vibration. Conduct the vibration test with the
modem circuit card assembly positioned on an appropriate adapter
affixed to a vibrating machine that is capable of providing the
amplitudes and frequencies specified in 3.3.3. Unless otherwuse
specified, the test equipment shall be in accordance with the
"Test Facilities" requirements of Mil-F-13926. The applied motion
shall be in two separate planes for the time period specified.
Upon completion of the vibration sweep the assembly shall be
removed from the vibration adapter and shall be subjected to the
tests in 4.6.3.It shall meet the requirements of 3,2.1.1 and
