3.7 Electromagnetic interference and compatibility.
3.7.1 Electromagnetic characteristics. The complete vehicle, equipped with the AN/VRC-12
radio set, AN/VSS-1, 2.2 kw searchlight, AN/VIC-l intercommunications set, and the M13A4
ballistic computer shall meet the requirements of MIL-STD-461 to the extent specified herein
18.104.22.168 Radiated emissions. Radiated emissions shall not exceed the limits specified herein
at a six meter distance from the vehicle (see 4.8.1).
22.214.171.124.1 Narrowband emissions. Narrowband radiated emissions shall not exceed the limits
of requirement RE02.1, MIL-STD-461A (see 4.8.1).
126.96.36.199.2 Broadband emissions. Broadband radiated emissions should not exceed the limits
specified in table X over the frequency range of 1.5 to 1000 megahertz (MHz) (see 4.8.1).

188.8.131.52 Radiated susceptibility. No equipment or subsystem, as installed in the complete
tank system, shall experience any undesirable response, malfunction, or degraded performance
when the complete tank system is subjected to the radiated susceptibility requirement RS03 for
sheltered systems in the frequency range of 10 kilohertz (kHz) to 400 MHz (see 4.8.1).
184.108.40.206 Electromagnetic compatibility. No equipment or subsystem as installed in the
complete vehicle system shall experience any malfunction or degradation of performance which
would impair mission success when other equipment or subsystems are individually or
collectively operated. Rotation of the image of the night vision device shall not be considered
degrading to mission success (see 4.8.1).
