EMCO/ETS-Lindgren 7405 E/H Near Field Probes

The EMCO / ETS-Lindgren 7405 E/H Near Field Probes are a passive, near field probe set designed as a diagnostic aid for locating and characterizing sources of E and H Field emissions. The set consists of three loop probes, one stub and one ball probe, an extension handle, an optional battery-powered preamplifier, and a foam-lined carrying case with a manual and application note.
 

The handle of each probe terminates in a BNC connector. Probes are designed to be used with a signal analyzing device such as an oscilloscope or spectrum analyzer. The optional preamplifier is useful when signal amplification is necessary for the analyzing device.
 

The loop probes are H-Field selective and directional. Sensitivity is relative to loop diameter. For example, the 6 cm loop can be used to make a general survey for H-Field emissions, while the smaller diameter loops can isolate specific sources.The ball and stub probes are E-Field selective and omni-directional. The stub probe is designed for precise E-Field source location, such as signal traces or IC pins. The ball probe has a large sensing element and is capable of locating weaker signals.
 

Typical applications include locating and characterizing emissions from PCBs, ICs, etch runs, cables, cover seams, etc.
