Why can a 1 kHz scope capture my 15 MHz signal?
The speed rating of many scopes is the repetitive mode limit. However the single shot limit can be much lower, such as 10 MHz. This prevents the acquisition of signals faster 2.5 MHz. Your evaluation of digital oscilloscopes must incorporate each instrument’s analog bandwidth, digital bandwidth, and single shot limit, in addition to its repetitive mode limit.
