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!

Low Noise Converter for Radio Amateurs
-
The concept of software defined radios (SDR's) is becoming increasing popular in both commercial, military and Amateur Radio circles. In their basic form, the use simple front end filtering followed by a Quadrature Sampling Detector (QSD) with the post detection processing done in software using the sound card found in PC's. Several popular kits have been developed to introduce Amateurs to the concept.

The DCNTS is a two channel Phase and Amplitude noise analyzer. Its dual demodulator architecture allows the system to use cross-correlation to cancel its internal noise and limitation; it is like comparing the outputs of 2 systems and only display the similarities while rejecting differences. Its main extension is the Residual Noise measurement front-end which includes all necessary hardware to automatically measure residual noise on 2-ports devices either in RF frequencies or microwave. It could be a frequency multiplier or divider, an amplifier or any other phase coherent input to output device.

Noise Figure Measurements With Vector Correction
S96029B
-
This software application enables high-accuracy noise figure and noise-power measurements of amplifiers. It utilizes Keysight’s unique vector-source-correction technique, which uses a source-impedance tuner to remove the effects of imperfect system-source match. This approach yields accuracy that surpasses that provided by the Y-factor method and other cold-source implementations, especially for in-fixture, on-wafer, and automated-test environments. A scalar-calibrated method is also available that offers less accuracy but is faster and does not require an impedance tuner.

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.
