ABSTRACT
It is that one developed with development of the digital circuit is new-type oscillograph which stores the function that the figure stores the oscillograph . Original ancestors e some advantages of the good simulation oscillograph , the digital oscillograph can already be accomplished at prent, catching and is not repeating the signal, avoiding melting and glimmers specially emptily, reply the mark of eking from the incident of touching off on time of the signal --Realizing it in isolating the trouble in the circuit etc., the digital oscillograph demonstrates the incomparable advantage of the simulation oscillograph . So digital oscillograph becau performance , good performance price of advantage their, just coming out , demonstrated its strong vitality, all trades and professions needed urgently , there is its wide development prospect. .
