V1.0TBRE101TEKBOXDIGITAL SOLUTIONS30 Hz-100 KHz RE101 Loop Antenna1.IntroductionThe TBRE101 is a passive receiving loop antenna used in MIL-STD-461G RE101 testing to measure radiatedemissions from electronic equipment and subsystems,including electrical cable interfaces for defenseapplications.The TBRE101 is used to measure low frequency magnetic field emissions 7cm from all sides of the DUT.Thetest covers the frequency range of 30 Hz to 100 KHz.Section 5.17 of the MIL-STD-461G specifies the testsetup and measurement procedure.EUT47cmMeasurementReceiverTBRE101 Typical Test SetupThe TBRE101 consists of a 13.3 cm diameter coil with 36 tums 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 thecontained plane and creates a voltage signal proportional to the intensity of the B-field/H-field radiation at theloop's output port.A TekBox TBCCP1-2K70 coaxial RF current monitoring probe(transducer)with a flat transfer impedance of 0dBQ(1V/A)from 9 kHz to 30 MHz when loaded with 500 is an optional accessory for calibration purposes.1
