Introduction DJ3500

 

As the primary threat, Road-side Remote Improvised Explosive Device (RCIED) has caused serious causalities each year in many countries and immensely endangered their law enforcement agencies including counter-terrorism unit and bomb disposal squad. Safely and smoothly fulfilling the protection task for people’s lives and property by law enforcement departments has become a tremendous challenge to the security department of any country in the world.

 

 

Privis’ solutions—DJ3500, High Power DDS Convoy Jamming System, implementing the most effective and reliable RF jamming technology and equipped with a fully-integrated broadband jamming system. DJ3500 can cover, continuously and simultaneously, all the RF communication Frequencies 20MHz ~3600MHz.

 

DJ3500, full portable multi band DDS Jamming system, is designed with a ruggedized trolley type case ,light weight, high mobility and reliance. This device is configured with 5 different jamming modules. The jamming frequency can be more than 10 Bands. Jamming frequency module can be up to 250-300watt output power. The DJ3500 is especially easy to install and operate: simply attach the selected antennas and activate the desired frequency bands. All operating controls and LED indicators are externally installed. The unit operates from internal battery, or can draw power from AC mains or a suitable DC power source.

 

The general design of the system meets military requirements as well as international quality standards and requirements. Our industrial in-house quality management system guarantees highest quality standards in terms of performance, reliably and long-life cycles.

 

Based on our general design, we can further customize our systems to client-specified scenarios both for military and civil applications in order to provide the best individual solution.

Equipment Structure and Operating Principles

 

System Diagram:

 

 

 

Machine Body:

DJ3500 adopts DDS technology, fully sweeping the jamming frequency bands so that it results in a more efficient jamming and bigger shielding coverage. Enclosure with American Mil-spec Case, dustproof, shockproof and drop-resistance.
Modular design makes easier maintenance. Damaged modular can be took off and changed easily. It will not interfere the other modules’ normal working.

 

 

 

Characteristic Of Jammer Modules:

Each module is designed with three indication lights, to show Power, Run and Alarm (Antennae VSWR feedback status).
Each module is with LED display to indicate the working frequency, output power and etc.
Each Module is designed with 232 Com Port and USB cable, connected to the computer. Frequency bands and output power can be adjusted, and the working status can be monitored through this software.

 

 

 

REMOTE CONTROLLER:
DJ3500 is design with a wired remote control unit, facilitating the operator to manage each module in any situation. This remote control unit can also display both internal and external battery level as well as built-in power supplies’ working status.

 

 

 

DDS MODULE SOFTWARE INTERFACE:
DDS software interface is quite simply. The operators just move the mouse and then he can set up working frequency bands and output power of the modules. Each module can be up to 4 channels output at most.

 

 

 

BIGGEST ADVANTAGE OF APPLICATION:
DJ3500 can be portable and vehicle mounted, which it’s biggest advantage in the application. Two units of DJ3500 can combine full frequency bands installed in the vehicle, equipped with vehicle mount antennae as required.

 

 

 

BATTERY TECHNICAL PARAMETER
To warranty the safe operation of the equipment, Lithium Iron Phosphate battery has been selected. It is the most secure battery among the global large capacity batteries currently.
