Well isn't that neat.
For those of you who obtained an AFG (or several) you'll have not doubt noticed the multiple connection points on the back for the future expansion modules. Regarding this post I'm focusing on the Flux Capacitor pin set. The one with the pair of jumpers located at the top and bottom of the connection point.
These have to do with the resulting ANTI-MATTER waveforms. When you switch from their factory setting of 1&5 you'll obtain different (and sometimes not) versions of the anti-matter setting. 2&5 varied in portions of the cycle minus the square wave. I had little luck with 3&5 and have not yet tried any other combinations.
you can try other combinations yourself and see what you get. :)
