随着电子技术的发展,数字示波器获得了越来越广泛的应用,有代替模拟示波器的趋势。为了记录瞬变过程,最好采用数字式贮存示波器(DSO)。例如B&K Prelison Dynascan公司的2520型示波器每秒可取样2 M个点,每个通道拥有1 K×8 bit记忆能力。但是,由于数字示波器采用了记忆单元和模数转换器,所以投资稍多,因此同样带宽的数字示波器要比模拟示波器贵。采用新技术、新元件是模拟示波器
With the development of electronic technology, digital oscilloscope has been more and more widely used, instead of the trend of analog oscilloscope. To record the transient process, it is best to use a digital storage oscilloscope (DSO). For example, B & K Prelison Dynascan’s Model 2520 oscilloscopes can sample 2 M points per second, each channel has 1 K × 8 bit memory. However, because digital oscilloscopes use memory cells and analog-to-digital converters, they invest a little more, so digital oscilloscopes with the same bandwidth are more expensive than analog oscilloscopes. With new technology, the new component is an analog oscilloscope
