Tekbox TBRS101-TX 30 Hz – 100 KHz RS101 Loop Antenna

The MIL-STD-461G RS101 test determines the susceptibility of equipment installed in close proximity to large radiated magnetic fields, and their ability to withstand them in the frequency range 30 Hz –100 kHz.

The TBRS101-RX Field Monitoring Loop consists of a 4.1 cm diameter coil with 51 turns of 7 strand 41 AWG Litz wire inside a shielded body. The DC resistance of the loop winding is 4.1 ohms. The loop receives magnetic field radiation normal to the containing plane 5cm 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.

A TekBox TBCCP1-2K70 coaxial RF current monitoring probe with a flat transfer impedance of 0 dBΩ (1V/A) from 9 kHz to 30 MHz when loaded with 50Ω is available as an optional accessory for calibration purposes.
