Abstract
This paper analyzes the concept of analog input bandwidth of digital oscilloscopes,studies two measurement methods of analog input bandwidth,and builds a dedicated hardware platform for testing.An automated test is implemented.Three speci-fied oscilloscope products'bandwidth are tested,and the corresponding baud plot is obtained,verifying the feasibility of the method proposed in this paper.Both the hardware platform and automated testing method are not only applicable to analog input bandwidth of digital oscilloscopes,but also for various data acquisition products.
