Laird Technologies produces an extensive line of ferrite products for inductive and EMI filtering applications with a product line that includes ferrite EMI cable cores.
Laird Technologies' cylindrical EMI suppression ferrites provide a cost-effective means of reducing common and differential mode EMI. These cores are most frequently used to suppress common mode EMI on the internal and external cable assemblies of electronic equipment. By decreasing the levels of EMI radiated by internal cables, ferrite cores can reduce the cost and amount of overall shielding required to confine EMI within a product's enclosure. They may also be successfully used on power cables that carry digital or analog signaling.
To achieve maximum EMI filtering performance in a given application, select a ferrite with an inner diameter most closely matching the outer diameter of the wire or wire bundle to be filtered. The in-circuit impedance may be substantially increased by passing two turns of the wire conductor through the ferrite core. A typical common mode application might have two conductors passed through a ferrite core. With equal and opposite currents flowing through the core, zero net bias is established through the component, and maximum impedance is thus realized from the ferrite.

This 30MHz filter is recommended for any radiated emissions testing.
The High Pass filter will filter out all frequencies below 30MHz which are in the ambient noise during the pre-compliance or compliance testing.
Radiated signals below 30MHz can be high in magnitude, and can interfere with your testing or spectrum analyzer.
By putting an RF700 in front of your spectrum analyzer's RF input, you will be assured cleaner test results.
