There are two kinds of digital oscillosocpes: sampling and real-time. Real-time scopes attempt to capture a signal one sampme at a time and reconstruct it one sample after another. Thus, real-time scopes can work on any waveform. Sampling scopes sample at a slow rate but have very high bandwidth. Signals must be repetitive because the scope samples at different points on each cyle then reconstructs the waveform.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
