PURPOSE: A portable PLC(Power Line Communication) diagnosis device is provided to measure signal generation, spectrum analysis, and data communication analysis in real time. CONSTITUTION: A DSP(Digital Signal Processor)(30) modulates data which is inputted according to a control signal inputted from a center processing unit. The DSP executes an IFFT(Inverse Fast Fourier Transform) process of the modulated data for time domain data. The DSP executes an FFT process of frequency domain data inputted from a power line. The DSP modulates the frequency area data. A second memory(77) stores a program execution code for a serial processing process executed by the DSP. The second memory temporarily stores data which is generated with processing time. |
