  • ETS-Lindgren's Model 7405 E & H Near Field Probe Set is a passive, near field probe set designed as a diagnostic aid for locating and characterizing sources of E and H-Field emissions. The Model 7405 E & H Near Field Probe Set consists of three loop probes, one stub and one ball probe, an extension handle, an optional preamplifier, and a foam-lined carrying case with a manual and application note. The handle of each probe terminates in a BNC connector. These 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.
