MIL-PRF-83174E
4.6.13.3 CS115. A 30 Hz test signal, applied for one minute with a duty cycle of 50%, a pulse
width of at least 30 nanoseconds (ns), and rise/fall times of less than or equal to 2 ns shall be
used to test the transmitter using the test methods described in MIL-STD-461E, Section 5,
Method CS115.
4.6.13.4 CS116. The transmitter shall be tested with a test signal consisting of a damped
sinusoid with the following characteristics and the normalized waveform given in Figure 5 using
the test method described in MIL-STD-461E, Section 5, Method CS116.
e-(šft)/Q sin(2šft)
where: f = test frequency (Hz)
t = time (s)
Q = damping factor, 15 ± 5
The damping factor (Q) shall be determined as follows:
Q = (š(N-1)/(1n(IP/IN))
Where: N = cycle number (i.e., N = 2, 3, 4,...)
IP = 5 amps, peak current at 1st cycle
IN = peak current at Nth cycle
ln = natural log
4.6.13.5 RS103. The transmitter shall be tested with radiated electric fields with a limit of 10
volts per meter (V/m) from 30 MHz to 1 GHz and 60 V/m from 1 to 18 GHz using the test
methods described in MIL-STD-461E, Section 5, Method RS103.
4.6.14 Environmental tests. The transmitter shall be subjected to the following environmental
tests.
4.6.14.1 High temperature storage. With the transmitter de-energized, the transmitter shall be
exposed to a constant 160°F and a maximum relative humidity of 1% for 48 hours at normal
storage configuration. At the end of the 48 hours, while still at that temperature, the transmitter
shall pass the tests specified in 4.6.1 and 4.6.3.1 or 4.6.3.2, as applicable. The accuracy of the
output tolerance shall be ± 0.15V. This test may be performed in conjunction with the
temperature shock and vibration tests.
4.6.14.2 Low temperature storage. With the transmitter de-energized, the transmitter shall be
exposed to a constant -65°F for 48 hours at normal storage configuration. At the end of the 48
hours, while still at that temperature, the transmitter shall pass the tests specified in 4.6.1 and
4.6.3.1 or 4.6.3.2, as applicable. The accuracy of the output tolerance shall be ± 0.15V.
4.6.14.3 Temperature-altitude (cycling). With the transmitter de-energized, this test shall be
conducted in an environmental chamber at ambient conditions. The rates of temperature and
