Application：
● BJ-8601 test system includes a medium size anechoic chamber, and a compact antenna test range ( CATR) designed for mmWave OTA test in a lab environment, covers frequency range from 24 to 90GHz;
● The high precision reflector provides a large quiet zone size of 400mm for a black box testing;
● Combing with a high accuracy 4-axis positioner, the system is able to provide fast and accurate antenna measurement for various size DUTs up to 100 kg;
● Fast measurement capability via TTL hardware signal trigger;
● The CATR supports single or multiple feed antennas to measure different signals at the same time;
● The system is capable of switching between indirect far field and direct far field measurement method;
● Optional thermal enclosure is available for Extreme Condition from -40 to 100℃.
