If it is in a normal use environment, it is not complicated to install and debug the cell phone signal jammer. Generally, you only need to turn on the host switch after powering on the device, and use the mobile phone at different positions from the shielding device to observe the working status of the mobile phone, which can be very intuitive interpretation. 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 or formulate an adjustment plan on site. At the same time, it can fully reflect the importance of the spectrum analyzer to the installation height of the cell phone signal jammer. sex!

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 cell phone signal jammer for some mobile phone signals. . 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 cell phone signal jammer manufacturer will help to quickly find a solution to the unsatisfactory mobile phone signal shielding.

2. In the on-site environment, the layout of the building is complex, there are many partition walls or obstacles, and the signal coverage of the cell phone signal jammer is uneven. In such a field environment, if there is a spectrum analyzer, you can receive the shielded signal of the cell phone signal jammer through the receiving antenna and display it on the spectrum analyzer, and then observe the amplitude of the waveform on each frequency band or read the signal strength. The numerical 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 further adjusting the installation position of the cell phone signal jammer or the antenna orientation.
