Contains high frequency components of the cable, multi-point grounding method can be used, will the cable in the cable shield should be grounded at both ends, if possible, you can also add a connector in the middle of the shield to ground. For the audio shield sensitive circuits can only be grounded at one end of the cable shield to such places must be insulated to prevent unnecessary ground. XIII shielded room and the test method shield shielding effectiveness of shielding effectiveness of the engine room is usually defined as: For a given external source of interference shielding, in the shielded room before and after a certain point on the interference of the electric field strength or magnetic field strength ratio. China's current high-performance shielded room types of shielding effectiveness measurement methods are used MIL-STD-285 and LEEE-299-1969 standard. MCD-W433G cell phone jammer could work for a long time without stop.The shielding effectiveness measurement should pay attention to the problem: ☆ receiving sufficient field strength meter high sensitivity and frequency response, the field strength meter to provide domestic special section in the UHF and microwave sensitivity is poor, so that does not receive the weak signal. ☆ microwave signal source have enough transmit power, horn antenna have high emission efficiency. ☆ low frequency magnetic antenna should strictly abide by the production standards.
Five shield, make your computer faster! Find ways to allow the system to achieve speed start, has been the relentless pursuit of you computer enthusiasts.MCD-W433G cell phone jammer could work for a long time without stop under all circumstances. However, trying to boot the system to achieve speed, has been the relentless pursuit of you computer enthusiasts. However, when we use every trick to optimize the system, the kind of trick to optimize the system after the system startup screen progress bar still needs to turn the system back on to start several successful, this is how it happened, system startup screen The progress bar still needs to turn the system back on to start several successful, this is how it happened, is it all summed up the media system optimization trick is to "Bluff In fact, many hidden in the system the shadows of the network settings, types of system optimization trick is to Fudge "people? In fact, many dark hidden network settings in the system function of many systems Bluff? The manufacture process of MCD-W433G cell phone jammer was strictly processed with the ISO9001 quality system management.System optimization trick can not be touched, and in many cases because they slow down the network functions properly set the system boot speed; this, and in many cases is inappropriate because these settings are network functions slow down the boot speed; as this, we just such improper network function blocked, the system will be able to take the lead together with speed! Blocked, we will be able to take the lead for the system coupled with speed! 1, the shielding network sharing, screen sharing network if the computer is not in our local area network unit, if not in our computer and local area network unit, then the network has been enabled sharing in fact, are not useful, useful no, it's there but will drag the system's boot speed;Only within 5 seconds after switching the cell phone jammer on, it works. in order to improve system boot speed as much as possible, then it will drag in the system's boot speed; as much as possible in order to improve system boot speed, we can be local system has enabled network sharing to block out, the following is a specific mask steps: sharing function to mask out, the following is a specific mask steps.
