Abstract

The present application discloses an attenuation temperature drift method and a digital oscilloscope for a digital oscilloscope. The digital oscilloscope includes an impedance transformation network, an attenuation network and an offset adjustment circuit. First obtain the vertical scale setting value of the digital oscilloscope; then attenuate or amplify the bias voltage signal output by the bias adjustment circuit according to the vertical scale setting value, and output the attenuated or amplified bias voltage signal to the impedance transformation network , so that the impedance transformation network superimposes the attenuated or amplified bias voltage signal and the output signal of the attenuation network, so that the temperature drift phenomenon when the digital oscilloscope displays the waveform is attenuated. Since the bias voltage signal is adjusted according to the vertical scale setting value, the temperature drift phenomenon is attenuated, thereby enhancing the waveform display effect of the digital oscilloscope to improve user experience.
