I've previously posted about working on an RF attenuator to better test WiFi systems. Today we officially released this, including Arduino source code and Eagle PCB layout files for the Arduino shield. I believe that anyone could use this code and PCB files (and appropriate components) to build an Attenuator if they so desired. Links to source code and other info is below. http://bens-workshop.blogspot.com/2012/11/lanforge-attenuator-v10-is-complete.html Thanks, Ben -- Ben Greear <greearb@xxxxxxxxxxxxxxx> Candela Technologies Inc http://www.candelatech.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
