1、 Product Introduction
The ZJSC-SDR16 portable frequency jammer is widely used in scenarios that require wireless signal control, such as bomb disposal, counter-terrorism, and technical investigation. It can effectively block signals from remote control devices (including drones and unmanned vehicles), digital intercoms, 2G/3G/4G mobile phones (TD-LTE and FDD-LTE), 5G mobile phones (broadcasting 700MHz frequency band, 2.6G \ 3.5G \ 4.8G \ 4.9G), analog and digital cordless phones, Bluetooth, 2.4G/5.8G WI-FI, etc.
2、 Composition and Function
The frequency interference meter mainly consists of a host (including a system main control unit, signal excitation unit, power amplifier unit, fan component unit, built-in rechargeable lithium battery pack, power management unit, etc.), a portable pull rod outer box, and omnidirectional antenna components, LCD
Composed of touch unit, cable, user and maintenance manual, spare accessories, etc.
The frequency interference meter can effectively block public mobile communication networks (2G/3G/LTE/5G), as well as unmanned vehicle/drone remote control and walkie talkies, WiFi， Wireless signals such as Bluetooth.
3、 Advantages of frequency interference meter
