The PBS 2 from Aaronia AG is an RF Near Field Probe Set that operates from DC to 9 GHz. It includes a total of 5 probes: 4 probes for magnetic field measurement and one for measurement of electric fields. All probes are covered with an insulating layer, thus allowing the safe measurement of oscillators or mains lines. The PBS2 probe set additionally contains a high-performance pre-amplifier, allowing measurement of significantly weaker interference sources and boosting the sensitivity by up to 40 dB. All probes have deliberately been implemented as passive devices to make them usable as transmitting devices as well which allows components and circuits sensitive to interference to be easily pinpointed. It is available in a case that measures 300 x 190 x 70 mm.
