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 vicinity of sources of electromagnetic radiation.
They serve to locate and identify potential sources of interference within the building blocks of electronic assemblies.
The probes work similarly to broadband antennas and pick up radiated emissions from components, PCB traces, enclosure openings or gaps, and from other parts that may emit RF.
The probes are usually connected to a spectrum analyzer.
By scanning the probe over the surface of a PCB assembly or housing, locations emitting electromagnetic radiation are quickly identified.
By switching to a probe with a smaller size, the occurrence of emissions can be further reduced.
Additional applications are RF immunity tests by feeding an RF signal into the probe and emitting it to potentially sensitive circuit sections: In addition, the probes can be used in the field of repair or troubleshooting to trace problems in RF signal chains by non-contact measurement of RF signal levels .
Another application is the non-invasive measurement of RF building blocks such as modulators or oscillators.
Frequency, phase noise and spectral components can be measured in conjunction with a low noise preamplifier.
The TBWA2/40dB broadband amplifiers are connected between the EMC probe and the Spectrum Analyzer to increase the dynamic range of the measurements.
Each set contains one SMB to SMA cable (0.75m)
