Embedded or External Controller? Go ask Alice

“…when logic and proportion have fallen sloppy dead” – Jefferson Airplane

In my recent article about integrating traditional and modular instruments I touched on the subject of controller strategy and the choice between using an embedded controller or an external controller.  What can the classic song White Rabbit tell us about when to use each? Plenty. It is all about logic and proportion.

[RF] Space, The Final Frontier

“These are the voyages of the starship PXI. Its five-year mission: to explore strange new applications; to seek out new markets and new segments; to boldly go where no modular platform has gone before.”

One of those new worlds is Planet RF, orbiting around a dual sun system of Mil/Aero and Wireless Comms. Strange names they’ve adopted in this particular solar system!  Planet RF is sending out distress signals that has gotten the Federation’s attention.  Things are changing rapidly on this planet.

Cue the background music, and join me here on the voyages of Starship PXI!

Getting Small. Does one modular standard beat the others?

In my last blog post I summarized the advantages of downsized instrumentation.  More portable, more flexible, higher performance, and lower overall cost were all advantages depending on the application.

It’s pretty clear that modular instrumentation delivers significant space savings over traditional instruments through the elimination of keyboards, displays, and redundant power supplies.  But let’s look specifically at the modular systems themselves.  There are three open modular standards today: VXI, PXI, and AXIe.  Does one clearly deliver greater size reduction than the others?
