RE101 Loop Antenna TBRE101 30 Hz to 100 kHz
The TBRE101 is a passive receiving loop antenna used in the MIL-STD-461G RE101 test. It is employed 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 at a position 7 cm around the device under test (DUT). The test frequency range is from 30 Hz to 100 kHz. The test setup and measurement procedures are specified in Section 5.17 of MIL-STD-461G. The TBRE101 consists of a coil with a diameter of 13.3 cm, wound 36 times with seven strands of 41 AWG litz wire inside a shield. The DC resistance of the loop winding is 10Ω. This loop receives magnetic field radiation that is perpendicular to the internal plane and generates a voltage signal at the loop's output port that is proportional to the intensity of the B field/H field radiation. As a calibration option accessory, the TekBox TBCCP1-2K70 coaxial RF current monitoring probe (transducer) is available, which has a flat transfer impedance of 0 dBΩ (1V/A) over a frequency range of 9 kHz to 30 MHz at a 50Ω load.
