This demonstration is obviously just a starting point.
Rfi detection equipment.
Rfi testing uses a frequency range of 30 mhz to 3 000 mhz.
Similar equipment could be used to conduct much more extensive interference detection tests.
In my experience the 40 meter band seems to be where that sort of rfi is the strongest.
Larry and i developed filters that decreased the rfi from s 9 40 db to s 5 as measured on my ic 7000 from a short distance a b recently an employee from the local power utility company said that about half of his rfi complaints were from grow light ballasts.
Rfi to electronic equipment is a frustrating problem and many times an indication of a hazardous condition.
Identifying sources of radio frequency interference around the home most people associate radio frequency interference rfi with electricity that is arcing through the air as when a power connector is corroded or has become loose.
Radiated rfi is most often found in the frequency range from 10 ghz to 30 mhz.
The government is looking to buy radiation detection equipment rde to deter and detect illicit trafficking of radioactive materials across international borders border crossings integrated check posts icps and land ports will be equipped with rde to stop any smuggling of material needed for a nuclear device or radiological dispersal device said officials.
Rfi may prevent reception altogether it may cause a temporary loss of the desired signal or it may affect the quality of the sound or picture produced by your equipment.
He is a co author of the popular emc pocket guide and rfi radio frequency interference pocket guide.
Tektronix also offers other features such as mapping and the spectrogram display feature which are beyond the scope of this article.
How to find it and fix it isbn 0 87259 375 4.
If the equipment being tested has the potential for radiation above 3 000 mhz the frequency range of the rfi tester can be extended for particular measurements.
Electrical and electronic equipment can have defects that result in rfi without ceasing to function.
This radio frequency interference rfi and resolution guide is designed for users with a moderate to high level of electrical electronic or telecommunications knowledge skill and experience.
Radio spectrum management rsm has produced this self help guide to locating and identifying rfi sources.
Fortunately there is a solution.
A radio is an excellent detector of whatever frequency it is tuned to.
