Mixed Signal Debug Using a Mixed-Signal Oscilloscope
应用文章
Many of today’s designs include microprocessors and digital signal processors (DSPs) that combine analog signals with digital content. Debugging a mixed-signal design often includes correlating important handshaking activity while simultaneously verifying the analog components of the system. The digital signals in a design can be very fast, while the analog signals tend to be much slower. Viewing and analyzing the many signals of interest within a microprocessor or DSP-based embedded design can be difficult or impossible using a conventional 2- or 4-channel digital storage oscilloscope (DSO). The increased complexity and faster digital speeds of clock rates and edge times require oscilloscopes with more channels and higher bandwidths.
