Low Noise Amplifiers
-
Our range of ITAR Free, Low Noise Amplifiers (LNAs) cover a variety of applications but are primarily suited to airborne, maritime and ground based radar systems. LNAs are primarily intended to minimise added noise whilst providing high gain so design focusses on the parameters associated with the noise response of the amplifier. They are usually the first amplifier in the Radar detection chain and will have the lowest noise figure.

Dual, Low Noise, Coaxial Cable Optimized
DCOAX
-
Very high precision, three-terminal capacitance measurements can be affected by the self-inductance of the test cables, mainly at higher capacitance values. Magnetically induced noise can also reduce the quality of measurements. The cable now offered by Andeen-Hagerling both minimizes these problems and provides a way to standardize the residual self-inductance.

Noise Meters
-
Here you will find a full range with an industrial standard noise meter / sound meter to suit every requirement. With the portable noise meter you can carry out measurements quickly to gain control of a situation or to set the sound meter to take timed measurements. The noise meter is important for all industries, especially by using it as a mobile noise meter 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 10 pm in excess of what local laws permit. A noise meter / sound meter will help here.We can assess which noise meter or sound meter you require in relation to the issue you have and the relating laws (requirements regarding a sound meter and a sound meter’s usage vary depending on the country). We also have noise meter microphone extension cords, tripods, sound meter calibrators and calibration certificates for most noise meter models.

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!
