MULTI-TRACING DISPLAY INTERFACE DEVICE OF OSCILLOMETER

The utility model relates to a multi-tracing display interface device of oscillographs, which is composed of a clock pulse generator (multivibrator) 1, a logic signal generator 2, a logic signal buffer 3, an electronic switch 4, an adjustable step wave generator 5 and an integrated amplifier 6. The device enables a monotrack oscillograph to simultaneously display at most 8 tracks of analog or digital signal waveforms without any modification of an existing oscillograph. The gate time is continuously adjustable, and any track waveform displayed can independently carry out Y axis shifting. The device only transfers Y axis signals to the oscillograph after receiving multi-tracing measured signals, and enables the oscillograph to give full play of all the original functions of channels of Y axis and X axis.
