New advances in Infiniium oscilloscopes make them a combination of three instruments: a scope, logic analyzer and protocol analyzer. This gives you several advantages. First, you'll need less space on your bench and less time for set-up. Also, using a single instrument with both serial and analog capabilities, you can trace serial problems back to their root cause - just point to a protocol issue and the screen displays the corresponding waveform. In addition, the latest Infiniium models support not just one protocol, but a range of the most popular ones. So how can you best put these capabilities to work to debug serial designs?
