EMC Near-Field Probes

Conduct EMC Pre-compliance Testing with the TekBox TBPS01 EMC Near-Field Probe Kit

Read Online:

The TekBox TBPS01 includes a set of magnetic field and electric field probes for radiated emissions EMC pre-compliance measurements. The EMC probes are used in the near field of sources of electromagnetic radiation and serve to locate and identify potential sources of interference within the building blocks of electronic assemblies. The EMC probes act similar to 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. When used, these EMC probes are typically connected to a spectrum analyzer.

Key features
  • Slim design allows you to access tightly spaced components
  • Shielded loops help you avoid picking up common mode noise; not sensitive to the human hand
  • Frequency range up to 6 GHz
  • Insulated with rubber coating
Applications
  • Radiated EMC measurement
  • RF immunity testing
  • Contactless (load free) relative measurement of RF signal chains
  • Contactless (load free) relative measurement of oscillators, modulators, etc.
