<p>PURPOSE:To observe a desired signal by providing function setting an input signal selection circuit and the setting condition at the time of observation in connection with signal selection and selectively changing over a desired signal. CONSTITUTION:When the selection of one channel is required with respect to an observation condition control mechanism 8, a probe 10 is selected with respect to an input signal selection circuit 7 to emit a predetermined signal to a multiplexer 2. The relay corresponding to the multiplexer 2 is closed and, at the same time, data for setting an observation condition is sent to an observation condition setting mechanism 9 from the control mechanism 8. The setting mechanism 9 receives the data from the control mechanism 8 to set a vertical axis range setting part 3, a horizontal axis range setting part 4 and a coupling setting part 5 and a desired signal can be observed on a signal display part 6. By this constitution, an apparatus having function automatically set to a preset range is controlled and the signal observation of a plurality of observation points can be efficiently carried out.</p> |
