The ETS-Lindgren (EMCO) 7405 E & H Near Field Probe 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 devices such as an oscilloscope or spectrum analyzer. The optional preamplifier is useful when signal amplification is necessary for the analyzing device.
ETS-Lindgren (EMCO) 7405 is 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 devices 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 locations, such as signal traces or IC pins. The ball probe has a large sensing element and is capable of locating weaker signals.
Typical applications for the ETS-Lindgren (EMCO) 7405 Near Field Probe Set include locating and characterizing emissions from PCB’s, IC’s, etch runs, cables, cover seams, etc.
