Hi Sanjib. Good point. Maybe it's not as useful but it sure is a fun idea. A good gift idea for the electrical engineer.

Well, you would certainly get a longer battery life with the phone sized form factor. I would assume that you aren't going to have it in scope mode all the time though so the watch should last much longer. Then again, I don't want to have to charge my watch a couple times a week.

It is a cool design. I went through the webpage and it might appeal every EE. But does it make a business case?...I don't think so. Why would I need a scope/waveform generator in a watch? Again, talking about the power it takes, "When using the oscilloscope, the battery will last about 12 hours"...does it make sense for it to be in a form of an watch? Why not a pocket oscilloscope in the size of a phone or perhaps using the phone, with better specs & a bit bigger display, with more buttons/nobs? Would it be so difficult to carry if it comes in the size of a mobile phone?

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.
