4.5 Test Procedures
4.5.1
Test Conditions. Unless otherwise specified, all tests shall be performed at ambient
temperature, pressure, and relative humidity as specified in the general
requirements of MIL-STD-202. Tolerances for test conditions shall meet the
general requirements of MIL-STD-202 and MIL-STD-810.
4.5.2 Visual Examination. Specimens shall be visually examined to ensure conformance
with 3.1, 3.4, and 3.5 of this specification.
4.5.3 Functional Tests
4.5.3.1 Box Coupler Input Impedance (see 3.6.1.2). Input impedance shall be
measured as described in MIL-STD-1553B at room temperature and at
the temperature rating extremes.
4.5.3.2 Box Coupler Waveform Integrity Test (see 3.6.1.3) Box couplers shall be
tested using the test configuration shown in Figure 1. The maximum
terminal output voltage of 27 V p-p shall be applied at point A using the
wave- form specified in MIL-STD-1553B, paragraph 4.5.1.5.1.1.2 (250 kHz
frequency). Droop, overshoot and ringing shall be measured on the bus
leads at point B.
Figure 1 Box Coupler Waveform Integrity Test
4.5.3.3 Box Coupler Maximum Voltage Test (see 3.6.1.4). Box couplers shall be
tested using the test configurations shown in Figures 2 and 3,
respectively. The maximum terminal output voltage of 27 V p-p shall be
applied at V1 using the 250 kHz waveform described in 4.5.3.2. The
output voltage shall be measured at V2. This test shall then be repeated
using a 1 MHz waveform similar to that described in 4.5.3.2.
