EMC Near-field Probe Set with 40 dB Wideband Amplifier
The
H20, H10, H5 and E5 are magnetic field (H) and electric field (E)
probes for radiated emissions EMC pre-compliance measurements. Includes
40dB amplifier and SMB to SMA cable (0.75m).
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 as wide bandwidth antennas, picking up radiated
emissions from components, PCB traces, housing openings or gaps and from
any other parts that could be emitting RF. The probes are usually
connected to a spectrum analyzer. Scanning the probe over the surface of
a PCB assembly or housing quickly identifies locations which emit
electromagnetic radiation. By changing to a probe with smaller size, the
origination of the emissions can be further narrowed down.
Additional
applications are RF immunity tests by feeding a RF signal into the
probe and radiating it into potentially susceptible circuit sections:
Furthermore the probes can be used in the field of repair or debugging
to track down issues in RF signal chains by contactless measurement of
RF signal levels. One more application is 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 TBWA2/20dB and TBWA2/40db wideband amplifiers
are connected between EMC probe and Spectrum Analyzer to increase the
dynamic range of the measurements.
