What you can't see can hurt you [oscilloscope

Abstract

Engineers live in fear of the unknown. Any problem or trade-off, if adequately managed, can be mitigated by the engineer's skill. The problems that you don't see - which may be intermittent signal anomalies, such as glitches - become increasingly expensive as they propagate to quality testing, manufacturing or to your customers. A fast update rate -a frequently misunderstood characteristic -is critical to your oscilloscope's ability to display these problems. How an oscilloscope captures and displays signals can make a big difference to your ability to track down glitches.
