Broadband Coaxial Noise Sources
Our integrated noise modules contain all the required biasing circuitry and only need a positive voltage to activate for an easy installation. Since they typically do not contain amplification, the raw noise output from the diode is seen at the output of the module resulting in a maximum ENR of approximately 35dB. Primary applications include system built-in test and laboratory use.

Noise Dose Meters
Here you will find a full range with an industrial standard noise dose meter to suit every requirement. With the portable noise dose meter you can carry out measurements quickly to gain control of a situation or to set the device to take timed measurements. The noise dose meter is important for all industries, especially by using it as a mobile device which is able to assess office stress levels or street noise levels.Often problems arise from noisy neighbors or if bars and restaurants are in residential areas and produce noise levels after 10pm in excess of what local laws permit. We, of course, can assess which noise dose meter you require in relation to the issue you have and the relating laws. We also have microphone extension cords, tripods, calibrators and calibration certificates for most models of noise dose meter.

Noise Location Package
Type HFDF
National RF’s Type HFDF high frequency location system is a proven noise hunting and location directional antenna system that allows you, in many cases, to walk right up to the source of High Frequency (HF) noise! Used by several power companies around the United States, professional noise hunters, and other communications specialists, the HFDF has located noise sources that emanated from pole power transformers, arcing electric fences, CATV in-line amplifiers, plasma TV screens, and even Marijuana grower’s heating lamps! The system incorporates several plug-in, tunable magnetic loop sensors of a proprietary National RF design, that cover the frequency range between 1.8 MHz and 55 MHz. The unit is packaged in a hand-held, lightweight metallic enclosure, with a pistol grip and a magnetic compass mounted on top. The compass is used to get magnetic bearings to the noise source, which may be plotted on a map to triangulate, and ultimately pin-point, the location of the noise source. In certain cases, our customers tell us that they have been able to walk right up to the interfering noise source and correct the situation on the spot!
