Abstract: It is known to provide measuring instruments, such as oscilloscopes or other measuring instruments, with analog adjustment elements for adjusting various parameters, such as the horizontal and vertical position of a signal (s1, s2) to be displayed, of trigger devices, etc. A digital measuring instrument is disclosed having digital adjustment elements in which the reaction behaviour of the parameters to be set substantially corresponds to that of a measuring instrument with analog adjustment elements. For this purpose, the adjustment elements are constructed as rotatable pulse generators and the measuring instrument is provided with a pulse processing device by which the pulse duration (T, T') of the pulses generators is determined. Thus independently of the rotational speed, a parameter reaction behaviour can be set by this device which results in a natural reaction behavior similar to that of analog adjustment elements.
