Cell phone signal jammer technical specifications
In some situations where the use of mobile phones is not allowed, if you take out your mobile phone at this time, it will show that the mobile phone has no signal. This is because a cell phone signal jammer is installed in the situation. With it, cell phone signals can be blocked. What are the technical specifications of this instrument? You may wish to base your selection on these indicators:
1. Isolation strength: also called isolation capability, pressure resistance strength or test pressure resistance. It refers to the voltage withstand capability between input and output, input and power supply, and output and power supply. The larger its value, the better the voltage resistance, the stronger the isolation capability, and the higher the filtering performance. This withstand voltage test is determined through the withstand voltage test of the signal blocker. During this test, a 50Hz power frequency voltage will be applied between the input and output, the input and the power supply, and the output and the power supply for several minutes, in order to determine that breakdown will not occur between the device and another potential surface. voltage value.
2. Accuracy: This is a yardstick for measuring the quality of a mobile phone signal jammer. The industry generally can achieve ±0.2% of the measuring range.
3. Temperature coefficient: Indicates the change in accuracy when the ambient temperature changes.
4. Insulation resistance: a numerical representation of the isolation DC effect between the internal power supply and the outer shell.
5. Response time: Characterizes the response speed of the mobile phone signal jammer.
6. Load resistance: reflects the load capacity.
When purchasing a mobile phone signal jammer, you can refer to the above technical indicators. We can do a test on this to help us use it more efficiently. Prevent adverse effects caused by signals. Make sure the instrument can shield the signal.
