Claims

[Scope of utility model registration request]

In a digital waveform recording device that converts an analog input signal into a digital signal and stores it, reads out the stored signal on an arbitrary time scale and records it on a recorder, etc., it has an input range setting section that sets the input range, and a trigger level. a trigger level setting section to be set, a display means consisting of a plurality of light emitting elements arranged in a row, and a position corresponding to the size of the plurality of light emitting elements to receive the analog-to-digital converted input signal; a decoder that generates a drive signal to selectively emit light from the light-emitting elements in the device, a modi multi-by-break that gives this drive signal a certain pulse width, and a decoder that takes the logical product of this drive signal and the brightness modulation signal. a second drive signal for selectively causing a light emitting element located at a position of the plurality of light emitting elements according to the magnitude of the trigger level set by the trigger level setting section to emit light; A digital waveform recording device comprising: a second logic circuit that performs a logical sum with the output of the first logic circuit and drives the plurality of light emitting elements with the output thereof.
