RF Test Solution

Electromagnetic reverberation chamber | BJ-7900

● For consumer electronic devices Sub 6GHz OTA test;

● For mass production test application.


BJ-7900, an electromagnetic reverberation chamber, is used for FATP OTA test on the 0.7~6GHz range;

● Comparing with the traditional stirrer solution, it can achieve a stronger and larger uniform field by multiple test probes. So it can support multiple DUTs test in parallel with little variance.

Main Features:

● Support wireless communication test, coupling test, OTA test;

● 4pcs DUT/box test in parallel, double the test efficiency;

● High efficient acquisition algorithm for processing the TRP with multiple test probes, instead of adjusting the antenna position by products. Achieve ±1dB accuracy;

● Support TX, RSSI, BER, BLER,FER, EVM, RSE and other test indicators;

● EMI filter on all data lines;

● Wireless communication with DUT. Avoid the USB impact to the antenna frequency response;;

● Manual or RS-232C/remote operation, suitable for automation line;

● Anti-pinch safety device, forced to open the drawer in case of resistance.
