This Near Field Probe Set contains 3-off magnetic (H) field probes, 1-off electric (E) field probe, a 40dB wideband amplifier (TekBox type TBWA2/40dB) and all interconnecting cables (RF and power) - Everything you need to get operational with a Rigol Spectrum Analyser.
The H20, H10, H5 and E5 are magnetic field (H) and electric field (E) probes for radiated emissions EMC pre-compliance measurements. The probes are used in the near-field of sources of electromagnetic radiation. They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies.
The probes act similar to wideband antennas, picking up radiated emissions from components, PCB tracks, housing openings or gaps and from any other parts that could be emitting RF energy. Scanning a probe over the surface of a PCB assembly or housing quickly identifies locations which emit electromagnetic radiation. By changing to a probe with a smaller size, the source of the emissions can be narrowed down further.
The probes can also be used for for RF immunity tests, by feeding a RF signal into the probe and radiating it into potentially susceptible areas of the circuit. Furthermore, the probes can be used for repair or debugging, to track down issues in RF circuits by non-contact measurement of RF signal levels.
The TBWA2/40dB wideband amplifier can be connected between an EMC probe and the spectrum analyser to increase the dynamic range of the measurements.
