A kind of oscillograph with waveform recording playback function

The invention provides a kind of oscillograph with waveform recording playback function, including：Waveform recording unit, for stored waveform data, obtains multiframe and records waveform；It is continuous to play knob, for producing corresponding angle message according to its anglec of rotation；The playing control unit is used to obtain corresponding interframe reproduction time interval and playing sequence according to the angle message；And according to the interframe reproduction time interval currently obtained and playing sequence, play the multiframe and record waveform.By the invention it is possible to when the frame number for recording waveform is more, rapidly continuously be played in multiframe records waveform, be easy to user's fast browsing；And it is possible to by adjusting knob angulation change interframe reproduction time interval and playing sequence, so that flexible dynamic regulation broadcasting speed and playing sequence.
