The importance of spectrum analyzer for the installation and debugging of mobile phone signal jammer
If it is in a normal use environment, it is not complicated to install and debug the mobile phone signal blocker. Generally, you only need to turn on the host switch after powering on the device, and use the mobile phone to observe the working status of the mobile phone at different positions from the shielding device, which can be very intuitive. The judgment read out the shielding effect. However, once you encounter a complex use environment, you need to use a spectrum analyzer to help when you need to analyze the signal on site or formulate an adjustment plan. At the same time, it can also fully reflect: the installation height of the spectrum analyzer for the cell phone signal jammer importance!
The complex usage environments we are talking about here can be roughly divided into two categories:
1. In the on-site environment, the base station signals transmitted from the mobile phone base station have various formats, and the signal strength varies greatly, resulting in the shielding effect of the mobile phone signal blocker for some mobile phone signals. shielding effect. At this time, if there is a spectrum analyzer on site, the technician can quickly find out which base station signal is stronger in such a live environment through signal retrieval, or analyze and determine which mobile phone frequency bands have no shielded signals. Complete signal suppression. Feeding this analysis result back to the manufacturer of the cell phone signal blocker will help to quickly find a solution to the unsatisfactory cell phone signal blocker.
2. In the field environment, the layout of the building is complex, there are many partition walls or obstacles, and the signal coverage of the mobile phone signal jammer is uneven. In such a field environment, if there is a spectrum analyzer, you can receive the shielded signal of the mobile phone signal jammer through the receiving antenna and display it on the spectrum analyzer, and then observe the waveform amplitude in each frequency band or read the signal. The strength value can accurately grasp the signal coverage strength of the shielded signal in each area, so that the expected signal shielding effect can be obtained in the corresponding area by adjusting the installation position or antenna orientation of the mobile phone signal jammer.
