When it comes to our signal jammer for sale, its shielding effect is when testing the product, open and close the box in the shielding box to obtain the signal value of a certain frequency range, and find the difference between the front and rear values, which is the shielding effect. The enterprise's DB difference is a negative number. If the negative value is smaller, the effect of the shielding box is better. Before testing the shielding effect, you must be fully prepared.
Due to the production volume regulations of signal jammers, the RF test processing process is usually processed and operated by many identical test stations in parallel. The success rate of one or some test processes is slightly lower; the reduction in output rate will lead to shortcomings in the production line and a sharp increase in product costs. In the final analysis, it can be divided into: design products or raw materials, test problems (mismeasurement problems), radio frequency imaging and other environmental factors.
Test uncertainty Signal jammer for cell phone is primarily based on interference signals/EMI in all electronic equipment industries. At this stage, it must encounter and solve a problem. Generally speaking, wireless communication products such as mobile phones, wireless receivers, wired routers, and wireless Bluetooth headsets. Wireless communication equipment and wireless communication modules such as Bluetooth headsets, wi-fi, wimax, data cards, radios, RFID, etc. are undergoing board testing and final testing, all through the use of radio frequency test shielding boxes. Improve the testing environment.
