Abstract

The invention discloses an integrated multi-port network instrument switch matrix control device and method, and the device comprises a main controller unit, a signal processor unit, a slave controller unit, a switch matrix unit, a storage unit, and a signal collection unit, and the main controller unit is connected with the signal processor unit and the storage unit. The signal processor unit isrespectively connected with the slave controller unit and the signal acquisition unit; and the slave controller unit is connected with the switch matrix unit. A switch of the switch matrix unit is anelectronic switch, and the service life of the electronic switch is longer than that of a mechanical switch. According to the invention, a control command is initiated by a main controller unit; the signals are analyzed and forwarded by the signal processor unit, the slave controller unit is used for decoding and executing, thereby finally achieving the flexible switching and configuration of theelectronic switches in the switch matrix unit, remarkably shortening the signal transmission path of the network instrument, reducing the insertion loss caused by a semi-rigid cable in the signal path, and improving the dynamic range of a system.
