Meeting Embedded Design Challenges with Mixed Signal Oscilloscopes

Embedded systems combine analogue behaviour, digital state and serial communications. A mixed-signal oscilloscope brings those views onto one timebase so an engineer can connect a corrupted transaction to its electrical cause, firmware…
