Communication Experiment Apparatus Using Programmable Logic Device

摘要

1. Technical Field of the invention defined in the claims; The present invention relates to a communication will exercise apparatus using a programmable logic device.; 2. Problems to be solved by the invention,; The invention program By using the logic device measures the waveform, the spectrum, the eye pattern and the error rate or the like, by integrating a number of independent modules, and greatly reduces the number of module boards, a personal computer without a separate instrument for each use It is found in the information measured by the monitor, and also it is an object to the user and provide the desired functionality to download a program written in a programmable logic device (down load) in a communication to check the operation unit exercises.; 3. Resolution of the subject matter of the invention,; The present invention, signal conversion means for converting an input signal into a digital signal; Transmission processing means for transmitting processed according to the user control information and the predetermined first select the signal transmitted the first control information stored in the first storage means from the signal conversion means to select in accordance with the control of the control means for the control information; After the second control information stored in the user control information and a predetermined second storage means selected in accordance with the control of the control means, processing means for channel distortion of the signal transmitted from the transmission processing means according to the selected control information; Select selected according to the third control information is stored in the user control information and the predetermined third storing means the control of the control means, in accordance with a radio frequency signal from the signal and an external transfer from the channel processing means for the control of the control means , reception processing means for reception processing in accordance with the selected signal to the selected control information; Receiving a user command, it controls the selection of the control information used by the transmission processing means, the processing means and the channel receiving processing means, and control means for controlling the selection of the reception signal processed by the reception processing means; And storing signals of the transmission processing means, the channel process means and received by the processing means includes a connection means for connection to the device.; 4. An important use of the invention,; The present invention is used for communication lab devices combine analog and digital.
