Troubleshooting embedded systems with multiple processors, sensors, actuators, communications and human interfaces, often demands more than the 2 or 4 measurement channels available on most oscilloscopes. More channels can help up to a point, but a mixed signal oscilloscope and clever application of digital channels can provide much broader system visibility. This Tech Brief specifically describes the use of FlexChannelTM inputs available on the 4, 5 and 6 Series MSO to address these challenges.
