To interface and associated verification requirements for the control of the electromagnetic interference (emission and susceptibility) characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use by activities and agencies of the Department of Defense.
Such equipment and subsystems may be used independently or as an integral part of other subsystems or systems.
PURPOSE.
For susceptibility measurements, the entire frequency range for each applicable test shall be scanned
frequency scan rates and frequency step sizes of signal sources shall not exceed the values listed in Table III. The rates and step sizes are specified in terms of a multiplier of the tuned frequency (fo) of the signal source.
Analog scans refer to signal sources which are continuously tuned. Stepped scans refer to signal sources which are sequentially tuned to discrete frequencies.
If a controlled video bandwidth is available on the measurement receiver, it shall be set to its greatest value. Larger receiver bandwidths may be used; however, they may result in higher measuredemission levels.
These bandwidths are specified at the 6 dB down points for the overall selectivity curve of the receivers.
Bandwidths.
NO BANDWIDTH CORRECTION FACTORS SHALL BE APPLIED TOTEST DATA DUE TO THE USE OF LARGER BANDWIDTHS.
