How to detect the effective function of frequency jammer?

  • 2022-04-28

What is the effect of frequency jammer? How to judge its actual effect. The simplest and most effective method is to directly test the ground power, shielding range and other data of the equipment on the spot through the spectrometer. If there is no such professional electronic detection equipment, you can also use multiple and different types of mobile phones, walkie talkies and other communication equipment to test the frequency jammer on the spot, which is not a method.

During the test, mobile phones of various brands and different operators can be prepared. After power on, the handheld mobile phone will detect the effective radius of the device from near to far from the position of the frequency jammer. From the position of the mobile phone away from the frequency jammer, check whether the mobile phone displays the number of signal cells, sends messages and makes calls at regular intervals. When checking whether the mobile phone is disturbed, it is necessary to make a call, because when the device is just turned on, the signal display on the mobile phone may appear false and not too accurate, so you can try to make a call. If you can't make a call, the mobile phone is still within the interference range, otherwise it is beyond the shielding range. During the test, it is recommended to detect the shielding distance in multiple directions of the jammer at the same time to test whether a certain point is within the working range of the equipment. Because the mobile phone is carried in this position for more than 2 minutes, the test is carried out to make the test result more accurate.

Compared with professional equipment, the test results through mobile phones are easy to understand, although they have certain limitations.
