MIL-PRF-32516
3.9.4 Stimulus input. If voltage and current is applied during the intermittent diagnostic
testing, the voltage and current provided shall not be injurious to the LRU/WRA.
3.9.5 Input power. The diagnostic equipment shall operate in accordance with the
nominal and alternate power sources requirements and listed in Table I.

3.9.6 Diagnostic equipment startup and power-on self test. When energized or restarted,
the diagnostic equipment shall run all power-on self-tests and be ready to operate in a typical
work center in less than ten minutes. The diagnostic equipment shall provide automatic
diagnostic information indicating whether it is operating within performance requirements. If the
equipment is outside the limits of the performance specifications, the information provided by
the self-test shall identify the likely cause of the fault.
3.9.6.1 Loop back test. The diagnostic equipment shall conduct a loop back test between
the diagnostic equipment input/output connections. The purpose of the loop back test is to
ensure the inter-connection harness between the diagnostic equipment and the LRU/WRA does
not have any open/short circuits. The time to conduct the loop back test is separate and in
addition to the startup and power-on self test.
3.9.7 Operating system. The operating system shall be an industry standard employing
a "windowing" graphical user interface.
3.9.8 Data transfer. The diagnostic equipment shall have the ability to transfer test data
(e.g., test results, wire signatures, and test programs) to an external device such as a memory
stick, hard drive, optical drive, or other computer.
