Signal energy, eliminate the unbalanced problem of energy caused by the change of each port load impedance.
In some embodiments, multiple programmable controllers are programmable attenuator.Thus, it is possible to according to signal of communication
Different pad values, by adjusting the parameter of programmable attenuator, draw corresponding deamplification.
In some embodiments, switch controller is further included, switch controller configuration multiple matrix switches in order to control
Switching.
According to the selection of matrix switch, adjusting switch controller can change matrix connection mode and matrix ports are corresponded to and closed
System, it is programmable to realize redefining for matrix connectivity port connection mapping, according to flexible configuration matrix type of attachment is actually needed, keep away
Exempt from path to fix, function is single, adapts to more scene application demands.
In some embodiments, control port is further included, control port is configured to by connecting external device to multiple
Programmable controller and multiple matrix switches are controlled.Thus, it is possible to by external device (PC machine) to programmable controller
Secondary development is carried out, and can realize parameter setting and the remote control to programmable controller and matrix switch.
In some embodiments, control port is cable port or radio port.Thus, can be according to different application ring
Border, chooses different control ports, may be such that the connection mode of controller connection external device is more flexible.
Brief description of the drawings
