Claims

[Claims for Utility Model Registration] In an oscilloscope having an auto-ranging function, a counting means for counting the number of pulses supplied to the input terminal of a sweep gate circuit during one sweep period;
The display waveform number setting means for setting the number of displayed waveforms compares the counted value by the counting means with the set number established in the displayed waveform number setting means, and compares the counted value with the set number in the comparison output [sweep time] /Display scale]
a first comparison means for controlling the control means; a detection means for detecting a value corresponding to the peak-to-peak value of the input signal; a [peak-to-peak (p-p) value/display scale] setting means; and a detection means. The value detected by [
Peak-to-peak (p-p) value/display scale] The value set in the setting means is compared with the value detected by the detection means in the comparison output.
p) Value/display scale] A second control means for controlling the vertical range control means so as to reach the value set in the setting means.
An oscilloscope characterized in that it is equipped with a comparison means.
