You make a stub antenna that's a quarter wavelength at the frequency you want to check for noise, and solder it to one of the device leads. Then expose to the RF, and it will dump the RF in the exact predictable spot. You desolder the antenna and solder it to different pins to get an idea of the response to injecting the noise into different pins. I thought it was quite clever. -- Paul Anderson VE3HOP wackyvorlon@gmail.com http://www.oldschoolhacker.com "May the electromotive force be with you." -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
