MIL-G-50351A (AR)
4.7.1.4
Temperature.
4.7.1.4.1 High (operating and non-operating).
This test
shall be performed as specified in Procedures I and II, Method
501 of MIL-STD-810 with constant temperature extremes as
specified in 3.3.4.
The operational checkout shall be as
specified in 4.7.2, 4.7.3, for compliance with 3.3.4.
4.7.1.4.2 Low (operating and non-operating).
This test
shall be performed as specified in Procedures I and II, Method
502 of MIL-STD-810 with constant temperature extremes as
specified in 3.3.4. The operational checkout shall be as
specified in 4.7.2 and 4.7.3 for compliance with 3.3.4.
4.7.1.5 Humidity (non-o perating). This test shall be
performed in accordance with Procedure-III, Method 507 of MIL-
STD-810 except that in Step 7, checkout shall be performed at the
conclusion of the test only, with the item at standard ambient
conditions.
The operational checkout shall be as specified in
4.7.2 and 4.7.3 for compliance with 3.3.5.
4.7.2 Electrical.
Continuity shall be inspected by
standard measuring equipment (see Table IV) and visual
examination for compliance with 3.4.
4.7.3
Performance.
Input and output characteristics. Adjust power
4.7.3.1
supply, item 1, to delivery input voltage of Table I, and connect
to fine pulse delay assembly as shown in Figure 1. Adjust pulse
generator (Table IV, item 2) to deliver input signal of Table I.
Connect pulse generator to fine pulse delay assembly as shown in
Figure 1.
Turn FINE DELAY ADJ control (R2) on fine pulse delay
assembly fully counterclockwise.
Connect oscilloscope (Table IV,
item 3) as shown in Figure 1.
Input signal of Table I should
appear on A channel, and output signal of Table I should appear
on B channel. Verify that output signal meets the requirements
of Table I.
FINE DELAY ADJ control
(R2).
4.7.3.2
Slowly turn FINE
DELAY ADJ control (R2) of fine pulse
delay assembly from fully
counterclockwise to fully clockwise,
and verify that delay of B
channel signal from A channel signal
varies from approximately
1
to approximately 10
