Tekbox TBRX101 Loop Antennas for MIL-STD-461G RE101 Testing
Tekbox TBRE101 Passive Receiving Loop Antenna
The Tekbox 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 7 cm from all sides of the DUT.
Tekbox TBRS101 Loop Antenna
The Tekbox TBRS101 loop antenna set consists of the TBRS101-TX radiating loop, TBRS101-RX field monitoring loop and ▸TBCCP1-2K70.
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 TBRS101-RX field monitoring loop receives magnetic field radiation normal to the containing plane 5 cm from the TBRS101-TX radiating loop winding and produces a voltage signal proportional to the intensity of the B-field/H-field radiation at the loop's output port.
