I remember at a trade show in the 90s, an engineer talked about a colleague who held up a PDA and asked him what it was. The guy replied that it was a Palm Pilot. His colleague said,"No, it's a 286 computer." That smart phone in your hand? It's got more processing capabilityand more memory than the early Cray computers. Think about it – a supercomputer in your hand. We live in amazing times.

Perhaps suitable for emergencies, but there are far better commercial products that can turn your mobile -- especially your tablet -- into not only a signal generator, but a logic analyzer, oscilloscope, spectrum analyzer, etc.

The idea is pretty good even similar product has been available in iTune store. The DIY mentality is very important for next generation to step up to the next big thing. ;)

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
