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
