The matrix device is matrix switch.Matrix switch is a kind of priority structure, it has gathered cavity body filter institute
Various test interfaces are needed, realize various test distinct interfaces, it is only necessary to which once mounting connection can be completed, and by interfacing order point
It is fitted on product, completes the various tests (power, intermodulation, S parameter ATE test) of product.
Three stations are incorporated into a station by filter integrated test system of the invention, and former filter production is surveyed
Examination needs three people of test man, and three stations occupy about 12 square metres of production site, first carries out power test, shifts after the completion of test
To intermodulation testing, be then transferred to ATE test, the testing time under whole Qualifications about at 40 minutes, if encountering bad products,
It can only know that certain single testing process is bad, without can know that whether other testing processs are qualified.After the technology of the present invention,
Same filter production test only needs one people of test man, and a station occupies about 4 square metres of production site, and the testing time about exists
20 minutes, and primary test can know the behavior pattern of former three testing processs, encountering unfavorable condition can disposably repair, efficiency
It greatly improves, enterprise's production capacity is obviously improved.
