4.7.3.4.3 Temperature effect on regulation. The variation in
output voltages shall be within the limits specified in 3.5.4.3 for
all tests conducted at other than ambient conditions.
4.7.3.5 Ripple voltage. With the input voltage set to 18.1 +/-
0.1 Vdc and using load resistors to produce the maximum load
currents as specified in Table II, use the oscilliseope (item 4,
Table V) to measure the peak to peak value at a bandwidth of 25 MHz
and the DMM to measure the true RMS value, verify that the ripple
voltages for all outputs do not exceed the limits specified in
3.5.5.
4.7.4 Environmental Stress Screeninq (ESS). The power supply
assembly shall be tested as specified in 4.7.2 and 4.7.3 after each
screening procedure for compliance with 3.6. After completing both
ESS procedures, perform the voltage adjustments as specified In
4.7.3.1.
4.7.4.1 Temperature Cycling. This screening procedure shall be
performed as specified in 3.6.1.1.
4.7.4.2 Vibration. This screening procedure shall be performed
as specified in 3.6.1.2.
4.8 Soldering. Soldering processes shall be inspected by
certified inspectors to the requirements and acceptance criteria of
MIL-STD-2000 to be specified is paragraph 3.8.
PACKAGING
