Engineers are running longer tests and capturing signals at higher sampling rates to reveal every detail. The result: a surge in data volume that demands high-capacity storage and fast processing to keep pace.

For time-varying signals, the oscilloscope is the most important measuring instrument. In addition to the basic capability of reading time and voltage parameters—which, although with greater difficulty, was also possible with analog instruments—digital oscilloscopes perform more advanced data processing as well.

A climate or temperature chamber is a device designed to simulate controlled environmental conditions. It allows the temperature and, if necessary, the humidity to be precisely set and maintained over the long term.
