At present, all electronic products are strictly in accordance with the GJB151B before the installation of the relevant tests, and in line with the standard requirements, but in the actual installation of the machine due to the interference between the various electronic components and the complex electromagnetic environment interference, resulting in the emergence of a variety of electromagnetic interference problems, and difficult to troubleshooting, affecting the delivery of the entire machine time.
The promulgation of GJB1389 series standard and GJB8848 provides a standard basis for the performance verification of the whole machine. In order to build a system that meets the requirements of system-level external RF electromagnetic environment sensitivity test, our company has been tracking the standard for a long time and accumulating experience, and now we have built and completed several sets of high-field-strength systems (self-research + delivery).
The 600V/m continuous wave system is the first set of completed high field strength system covering 1GHz-40GHz, and the delivery of the system marks that China has the ability to complete the 600V/m mean field of the external RF electromagnetic environment, which provides a strong guarantee for the test and verification of weapons and equipment.

External RF electromagnetic environment test system meets 1GHz-40GHz 600V/m continuous wave high radiation field strength test, consists of three standard 19-inch cabinets, equipped with the corresponding transmitting antenna and antenna bracket assembly, generates 600V/m continuous wave field strength (800V/m typical value) at a distance of 1m to meet the GJB1389A-2005 mean value field below 800V/m The test method meets the requirements of GJB8848-2016.

The system is equipped with Rflight's series of power amplifiers: 1GHz-2.5GHz/1000W, 2.5GHz-6GHz/600W, 6GHz-18GHz/320W, 18GHz-26.5GHz/100W, 26.5GHz-40GHz/100W, five bands of solid-state continuous wave amplifiers, and the corresponding antennas and other accessories. Composition.

External RF electromagnetic environment test system is the core product of our company, which is realised by high power broadband solid state solution with high reliability and friendly man-machine interface, and is applied in the field of system level electromagnetic environment.
