About：

The biggest feature of Beijing Daze Small Shield Test System ZN1188 is that it uses the built-in radiation source method to test the shielding effectiveness. It can test any small shield with a side length greater than 30cmx30cm30cm. Therefore, it fully complies with the national military standard GJB5792-2006 "Classification and Measurement Method of Electromagnetic Shielding Body for Military Secret Information System" and GB/T 39278-2020 "Measurement Method for Shielding Effectiveness of 0.1m～2m Shielding Shell". No matter you are measuring a shielding case, a shielding cabinet or a small shielding tent, you can easily measure the shielding effectiveness (9k-40G) of each frequency band. Customers who have bought it before, including large state-owned enterprises such as the China Institute of Metrology, have reported that the performance, appearance and usage have reached the level of similar foreign products, and it is very worth promoting. You think, if you need to go out for testing, ZN1188 is very convenient to carry. If you support domestic production, the ZN1188 small shielding body test system is original by the Chinese and has a Chinese invention patent. Compared with imported products, whether it is Both delivery time and after-sales maintenance have obvious advantages.

This test system is composed of several independently working power transmission sources and antennas. The transmission frequencies are 14kHz, 100kHz, 200kHz, 1MHz, 15MHz, 100MHz, 450MHz, 950MHz, 3GHz, 6GHz, 10GHz, 18GHz, 26GHz, 35GHz , 39.5GHz, etc.; within a specified distance, it can generate a port voltage with a magnetic field greater than 75dB and an electric field greater than 90dB. The size of the smallest measurable shielding case is 300mm×300mm×300mm for the detection of shielding effectiveness.
