The TBRS101-TX Radiating Loop is used to generate the low frequency magnetic field emissions. The distance between the winding and EUT is 5 cm. This is accomplished when the front edge of the the radiating loop comes into contact with the EUT faces during testing. The test is applicable in the frequency range of 30 Hz to 100 KHz. Section 5.20 of MIL-STD-461G specifies the test setup and measuring procedures.

The TBRS101-TX Radiating Loop is constructed of a 12 cm diameter coil with 20 turns of 12 AWG Gauge (2 mm) copper wire. The loop winding has a DC resistance of 50 mohms. The loop generates magnetic field strength or magnetic flux density normal to the containing plane by applying RF current to the input banana plugs.
