Automotive Testing Expo extends from squeaks to radar

摘要

The collocated Automotive and Engine Testing Expos in October featured fascinating technology such as micro-finished crankshafts and systems that applied antiwear coatings to cylinders. Great products, but not closely related to test. In contrast, both Yokogawa and Newton's 4th were displaying power measuring instruments, and Yokogawa also was showing the company's line of Scope-Corders. Keysight Technologies featured the Integra Vision power analyzers. Newton's 4th will soon be introducing a new machine. Like the present model, it can lock onto a signal within half a cycle-apparently something that not all analyzers can do. Readings will be inaccurate if the source continues changing speed, and the instrument never completely locks to it. Noisy PWM signals can be hard to measure for this reason.
