Direct drives place rigorous demands on position-signal quality. Optimum measuring signals increase the quality of the machined workpiece surface, reduce vibration in the machine frame, stop excessive ...

It’s easy to treat optical encoders as “black boxes” that need minimal consideration before they are installed to translate rotary motion into position or velocity feedback signals for a motion ...

The RS-485 standard defines a popular and widely used serial data interface and network that’s been in use for over 30 years. It’s found in factories, process control plants, building automation, and ...

Arbitrary waveform generators (AWGs) and other instruments with programmable analog outputs often let you use equations to create waveform points. Math functions in equations let you create “perfect” ...

To attain accurate positioning, a servo system requires a feedback signal to close its feedback loop. Instruments that typically supply the feedback signal include optical encoders, resolvers, and ...

Even in the best designs, noise and interference sneak in to reduce the signal-to-noise ratio (SNR), obscure desired signals, and impair measurement accuracy and repeatability. Digitizing instruments ...

Scientists have demonstrated a technique for the recovery of weak, noise-dominated optical signals. Weak optical signals are common in many science and technology applications. However, they are ...
