APREL have developed hand held antenna probes that can be used to sniff out problems on a circuit board that may be causing EMC noise. The antenna probes come in E and H field versions and can be used as either a receiver or method to excite a circuit.
These probes come in custom lengths and can be adapted very easily when required. Typical frequency application for each probe is from 100kHz to 6GHz all in one single package.
