The PMM PS-400 Near Field Probe set includes three probes: a tip probe, a broadband probe, and a H-field probe. The tip probe is a precision E-field probe that features the ability to singularly identify a problem trace or pin. It is designed to be extremely sensitive to distance from the source which allows easy discrimination between traces on a PCB. The broadband probe is designed to identify E-fields over a broad frequency range. The H-field probe’s magnetic loop design makes it ideal for isolating sources of magnetic noise.

Tip Probe

The tip probe is a precision E-field probe that features the ability to singularly identify a problem trace or pin. It is designed to be extremely sensitive to distance from the source which allows easy discrimination between traces on a PCB. The unique patented design allows measurement on individual traces as narrow as 3 mils.

Broadband Probe

The broadband probe is designed to identify E-fields over a broad frequency range. In addition, it has more amplitude sensitivity than the tip probe. Therefore, it offers a quick and efficient diagnosis of an emission source allowing the designer to discover and isolate trouble areas quickly.

H-Field Probe

The H-field probe’s magnetic loop design makes it ideal for isolating sources of magnetic noise. The shielded loop construction allows measurement to minimize the effect of electrical fields.
