History of jitter, Part 1: the early years

From the "History of Jitter" series over at Teledyne Lecroy:

Jitter is a signal-integrity gremlin that's been with us for a long time. In fact, it's been with us since before anyone really needed to care about it. But as time has worn on, our perception of jitter has certainly changed, and with it our approaches to diagnosing it, measuring it, and ultimately dispatching it.

Here, we'll begin a traversal of the "jitter story," surveying where we've been, where we are, and where we may be going in our dealings with the phenomenon.

There's no simple, straight path through the history of jitter. Rather, it's a story of numerous instruments, inventors, and twists and turns. We know, however, that it is borne of the ascent of serial data rates from a 45-baud telegraph receiver to the venerable 9-pin serial port to optical fiber carrying signals out to 160 Gbaud and up.

Along the way, we've seen real-time oscilloscopes, sampling oscilloscopes, time-interval analyzers, phase-noise analyzers, and bit-error-rate (BER) testers thrown at the problem in our efforts to understand and tame it....
