With the increase in the frequency of people using computers/home appliances/mobile electronic devices, the problem of computer radiation has become one of the topics of concern. Now there is a product called computer radiation eliminator on the market, many people are right. Its functions are diverse.
The radiation of electronic products is very much for many people to get rid of, because many people's work and life will deal with electronic products for a long time. As people's demand for electronic products expands, radiation eliminators come into being. Some people think that It has a remarkable effect, and some people are opposed.
Recently, a radiation eliminator has appeared on the network, claiming to eliminate low, medium and high frequency radiation generated by all electronic products, eliminating up to 98.8%.
The instrument, the relevant person expressed doubts, so in the RFsister RF space, an experiment on whether the product can eliminate radiation is in full swing, please see the following experimental process and results. (Here, thanks in particular, the test equipment and technical guidance provided by the RFsister RF space)
[Experimental conditions]
In a closed and undisturbed anechoic chamber (the ETS microwave darkroom below), some signals are transmitted (the signal generator below) and can be detected (the spectrum analyzer below). Then observe whether the detected signal changes when the radiation canceller is turned on or off; if there is a change, it has been eliminated.
[Experimental two groups]
experiment one
Pick 5 frequency points from 300~3000MHz to transmit signals.
Turn the artifact on and off,
Whether there is a change in the signal detected before and after observation;
Experiment 2
First test the working frequency of the artifact,
Then transmitting the signal in the band,
Turn the artifact on and off,
Whether there is a change in the signal detected before and after observation;
Experiment 1 conclusion:
Before and after the radiation canceller was turned on and off, no significant changes were detected in the information.
In other words, the radiation canceller did not counteract several frequency points collected by the experiment in this experiment.
Experiment 2 conclusion:
1. The working frequency of the radiation eliminator is 36MHz. The signals of other frequency points are detected from the spectrum analyzer, and the guess should be the frequency doubling signal;
2. When the signal generator generates the same frequency signal as the radiation canceller, the radiation canceller does not produce any offset effect;
3. After testing, the elimination instrument has no effect on the power amplitude of the radiation signal within 300MHz;
The experiment also made everyone fully aware that the false propaganda phenomenon on the market has been pervasive, and all we have to do is to present the results effectively and reasonably.
