This application note describes a closed loop, computer- controlled, variable attenuator for the control of output power from a tunable laser. It is based on the combination of a 1/2 wave-plate and a ...

A Pie control can analyze one, two, or three independent variables. The number of data dimensions must correspond to the number of independent variables in the analysis. To set the data dimension, use ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Variable primary chilled water systems can be a cost-effective alternative to standard primary/secondary systems and are becoming more commonplace for that reason. At the same time, these systems are ...

Only through proper troubleshooting and then solving the underlying problems can control loop performance be improved. Process design certainly plays a role in control loop performance, but experience ...

When it comes to making decisions among various automation technologies to perform a task, the answer is rarely clear cut. Ultimately, the decision is often tied to the specifics of the application ...
