E & H Near Field Probes Model 7405 Features: q Broadband Frequency Range Linear Response Locates both E and H- Field Emissions Sources Specialized Sizes / Shapes for Sensitivity Includes Free Carrying Case New Optional Preamplifier for Signal Amplification ETS-EMCO’s Model 7405 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 set consists of three loop probes, one stub and one ball probe, an extension handle, an optional batterypowered 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. Model 7405 Near Field Probe Set with New Optional Preamplifier sensing element and is capable of locating weaker signals. Typical applications include locating and characterizing emissions from PCB’s, IC’s, etch runs, cables, cover seams, etc. Three loop probes 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 HField 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 Carrying case Preamplifier ETS-EMCO’s Model 7405-907B preamplifier exhibits excellent gain characteristics across a broadband frequency range of 100 kHz to 3 GHz. The preamplifier enhances the sensitivity of spectrum analyzers, oscilloscopes and other receivers. The unit can be ordered with either Type BNC connectors or type N connectors. A wall-mounted power supply is included (please specify 110 or 220 VAC). Purchase as an option to the Model 7405 probe set or as a stand-alone product.

E & H Near Field Probes Model 7405 Stub Probe provides E-Field measurement near the signal source. Omni-directional Ball Probe identifies E-Field signals over a broad frequency range. Receiving Applications Radiating Applications Note: Power input to probe should be limited to a maximum of 0.1 watt to safeguard sensitive circuitry. Loop Probes offer varying sensitivities to H-Field emissions.
