ABSTRACT:
A signal analyzing means performs frequency sweep for input signals to be measured, and outputs vector data corresponding to sampling frequencies. The analyzing means supplies pulses to a sweep marker generating means at timings for causing the signal analyzing means to supply the vector data corresponding to the sampling frequencies to the display means. Whenever the sweep marker generating means receives a pulse from the signal analyzing means, it outputs address data for extending a sweep marker. The display means includes a CRT and displays a designated polar coordinate image on the CRT screen. The display means translates the vector data to address data of a position suitable for the polar coordinate image. The address data and sweep marker address data are superposed on polar coordinate data displayed on the CRT screen. The vector data and the sweep marker are simultaneously displayed on the CRT screen.
