The Type 7334-1 is equipped with an epoxy-glass base plate which serves as a spacer to enable the user to place the loop at exactly 7 cm from the face of the item under test as required by test procedure RE01 of MIL-STD-462.
Connection to the loop is through a BNC connector which enables coaxial cabling to the EMI receiver. The loop is supplied with a correction factor graph showing the values in dB which must be added to the reading of a 50 ohm EMI meter to obtain answers in either dB/μV/m or dB/pT. The correction factor decreases as frequency increases from 30 Hz up to approximately 15 KHz, where the factor levels off and remains relatively constant up to 5 MHz.
The Type 7334-1 Loop Antenna is required by Test Method RE01 in Parts 2 through 6 of MIL-STD-461C and RE101 of MIL-STD-461D. These portions of the specification require magnetic field emission tests of cables, equipment, systems and sub-systems installed in, or used in, all phases of military vehicles, ships, submarines, aircraft (including helicopters), spacecraft, or ground-based operations.
