SMALL E AND H FIELD ANTENNAS AND PROBES
These small antennas and probes are designed to measure the susceptibility of PCBs, ICs or small equipment to high levels of E and H fields. One use was measuring the susceptibility of the memory in an aircraft black box. The IC was powered by an external battery or battery and linear regulator external to the antenna containing the IC. The fields described here were achieved using a R&K A009K251-4949R 9kHz – 250MHz 75W power amplifier.
A step up/ step down transformer useful from 0.01MHz to 10MHz is available from EMC consulting and the calibration of this is supplied under Calibrations:
Using the step down feature with any of the H field antennas/probes a higher level of current and magnetic field is achieved.
Custom antennas can be manufactured with different dimensions and frequency range than those described here to suit the EUT or PCB size.
