PROBLEM TO BE SOLVED: To provide a signal monitor display device that can attain measurement/supervision/display of a base band signal with states such as a bit error rate, a block error rate, a reception signal level, a delay profile and a reception IQ constellation in the measurement and supervision of the signal states by a digital modulation-demodulation receiver. SOLUTION: The signal monitor display device receives data relating to base band signal processing from a transmitter-receiver, employs a conventional personal computer to analyze states of the signal such as a bit error rate, a block error rate, a reception signal level, a delay profile and a reception IQ, draws the signals on a screen to visualize the analysis result so as to allow a user to measure the relation of signal states and a time-base change. Moreover, the signal monitor display device stores the analysis result to a conventional recording medium and again draws the image of the stored measurement result on the screen as required. |
