The Aaronia PBS2 EMC Near-Field Probe Set for any spectrum analyzer and oscilloscope allows for straightforward pinpointing and measurement of interference sources from DC to 9 GHz in electronic component groups as well as execution and monitoring of generic EMC measurement. The sniffer set 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 safe measurement of oscillators or mains lines. The PBS2-5 PA probe set additionally contains a high-performance pre-amplifier, allowing measurement of significantly weaker interference sources, boosting the sensitivity of the instruments by up to 40dB. Perfect for locating interference sources which might have been found e.g. in an EN55011, EN55022 or EN50371 (Class A or Class B) survey. Should an interference source exceed an official EMC limit by 10dB, the probe set can easily verify if a certain countermeasure succeeds in making the circuitry conforming again. After implementing appropriate changes in the circuit, their efficiency can easily and reliably be verified. That way, expensive and time-consuming re-assessments in an EMC laboratory can be skipped.

All probes have deliberately been implemented as passive devices to make them usable as transmitting devices as well. Consequently, components and circuits sensitive to interference can easily be pinpointed.
