Description

<p>The difference between digital and analog oscilloscopes is explained by taking measurements of temporal profiles of optical pulses as an example. It is important to understand the basic principles of digital oscilloscopes, which convert analog input signals to digital data and store these discrete data in the buffer memory unit. To use a digital oscilloscope appropriately, the key points to be considered are sampling rate and memory length. Real-time arithmetic processing and single-shot measurement are also described as powerful uses of digital oscilloscopes.</p>
