Splitter of the present invention is by connecting multiple matrix switch, accessible site is integrated, multiple point-to-point signalling channel can be formed, therefore, can according to different testing requirements, connect different testing apparatuss, avoid by the more loaded down with trivial details problem of splitter point to point connect testing apparatus operation, signal uniform distribution can be avoided power information collection generation deviation by splitter.
According to an aspect of the present invention, also comprise multiple Programmable Logic Controller, Programmable Logic Controller is connected with splitter, and multiple Programmable Logic Controller processes the output signal of splitter and returned signal.
Thus, because multiple Programmable Logic Controller is connected on splitter, accessible site is integrated, when carrying out signals collecting, Programmable Logic Controller can process the output signal of splitter and returned signal, avoids and needs to reconnect different specialized equipment according to different collection signals and the problem of the complex operation caused.
In some embodiments, multiple Programmable Logic Controller is connected between splitter and matrix switch.
After balancing each node signal energy by splitter, regulate each attenuator not affect the signal energy of other branch road of splitter, eliminate each port loaded impedance and change the unbalanced problem of energy caused.
In some embodiments, multiple Programmable Logic Controller is programmable attenuator.Thus, according to the different pad value of signal of communication, by regulating the parameter of programmable attenuator, corresponding deamplification can be drawn.
In some embodiments, also comprise on-off controller, on-off controller is configured to the switching controlling multiple matrix switch.
According to the selection of matrix switch, by-pass cock controller can change matrix connected mode and matrix ports corresponding relation, realization matrix connectivity port able to programme connects redefining of mapping, flexible configuration matrix type of attachment according to actual needs, path is avoided to fix, function singleness, adapts to many scenes application demand.
In some embodiments, also comprise control port, control port is configured to pass connection external device and controls multiple Programmable Logic Controller and multiple matrix switch.Thus, secondary development can be carried out by external device (PC) to Programmable Logic Controller, and the optimum configurations that can realize Programmable Logic Controller and matrix switch and Long-distance Control.
In some embodiments, control port is cable port or radio port.Thus, according to different application environment, different control port can be chosen, the connected mode of controller connection external device can be made more flexible.
