LAPLACE INSTRUMENTS NEAR FIELD PROBES

The RF100 probe set consists of a passive E field probe and H field probe, BNC adapter and a carrying case. The output is via a BNC socket. These are general purpose probes which are ideal for use in conjunction with an EMC measuring system. They are sensitive to sources in close proximity, but are insensitive to background signals. This makes them ideal for the identification of emission frequencies in noisy environments… thus making measurements easier and quicker. The proximity requirement also enables sources to be located and the exit route identified.

Probes sets are available with two types of probe, E field and H field. The E field probe is sensitive to voltage induced (high impedance) radiation and the H field probe is sensitive to magnetic current induced (low impedance) radiation.

Notes:

• Near field probes are an essential part of the EMC test engineer’s toolkit. Near field probes are only sensitive to sources at close proximity. They are immunity to general background and other far field radiation
• They help to identify sources and in particular can identify potential radiation frequencies. Knowing which frequencies to look for can be a great help when measuring emission levels on an OATS.
• Near field probes do not provide any indication of compliance. They do not take into account the key contributor to radiated emissions, that is the effectiveness of the radiating antenna.
• When used as ‘sniffer probes’ they can help locate any leakage from screened  boxes or enclosures, and to indentify any cable that is acting as a radiating antenna.
