设备 - 示波器

Oscilloscopes are measurement tools that create a visual representation of electronic signals. An essential tool for those who work with electronics, they are used to observe and measure high-speed phenomena, with more advanced examples capable of measuring signals with frequency content approaching the GHz range. As a general rule they exchange absolute accuracy and measurement resolution for speed, with even modest multimeters likely to yield better measurements than most oscilloscopes of the DC/low-frequency phenomena for which multimeters are well-adapted.
