The TBRE101 is a passive receiving loop antenna used in MIL-STD-461G RE101 testing to measure radiated emissions from electronic equipment and subsystems, including electrical cable interfaces for defense applications.

The TBRE101 is used to measure low frequency magnetic field emissions 7cm from all sides of the DUT. The test covers the frequency range of 30 Hz to 100 KHz. Section 5.17 of the MIL -STD-461G specifies the test setup and measurement procedure.

The TBRE101 consists of a 13.3 cm diameter coil with 36 turns of 7 strand 41 AWG Litz wire inside a shield. The DC resistance of the loop winding is 10 ohms. The loop receives magnetic field radiation normal to the contained plane and creates a voltage signal proportional to the intensity of the B -field/H-field radiation at the loop's output port.
