MIL-DTL-62740A(AT)
b. Apply a HEXAD pattern 03 to P1-21 through P1-28, and apply the waveform of
figure 2.
c. An oscilloscope shall be used to verify that the square wave is present at U3-7,
delayed by no more than 490 ns.
d. Apply the waveform of 4.2.3.12 to P1-86.
e. Apply a HEXAD pattern 00 to P1-21 through P1-28, and apply the waveform of
figure 2.
f. An oscilloscope shall be used to verify that the signal at U3-6 is present at U3-7,
delayed by no more than 490 ns.
g. Apply the waveform of 4.2.3.14 to P1-66.
h. Apply a HEXAD pattern 01 to P1-21 through P1-28, and apply the waveform of
figure 2.
i. An oscilloscope shall be used to verify that the signal at U3-5 is present at U3-7,
delayed by no more than 490 ns.
j. Apply the waveform of 4.2.3.15.1 to P1-78.
k. Apply a HEXAD pattern 02 to P1-21 through P1-28, and apply the waveform of
figure 2.
l. An oscilloscope shall be used to verify that the signal at U3-4 is present at U3-7,
delayed by no more than 490 ns.
4.2.3.17 ATE test. To determine conformance to 3.3.17, install the PWA into TACOM
approved fixture (such as BTF-2500-03), on TACOM approved, ATE equipment (such as
HP 3062) with TACOM approved software and instructions (such as BSW-25000030).
4.2.4 Interface requirements verification.
4.2.4.1 Overall envelope inspection. Insert the PWA into the present existing location of
the test set, verify its envelope and interfacing conformance.
4.2.5 Ownership and support requirements verification.
4.2.5.1 Interchangeability inspection. To determine conformance to 3.5.1, the
interchangeability between different parts, subassemblies, and assemblies having the same military
part number shall be verified.
4.2.5.2 Identification marking inspection. Verify the presence of the required PWA
identification marking.
4.2.6 Operating environment requirements verification. The electrical performance tests
specified in 4.2.3 through 4.2.3.17 shall be conducted prior to and at the completion of each
environmental test. Verification of performance during the high temperature and low temperature
