     end

     action a2d 
         channel 0           // channel to grab
         range 2             // this is card specific voltage range use comedi test to find ranges ./usr/bin/comedi_test
         n_samples 1         // samples to grab
     end

     action mirror_pbp       // mirror scan point by point
         axis 0 -1 1 .1      // axis number, start, stop, increment
         tell_pos 2          // report position
         savedata            // force save data at the end of this loop (useful for live processing scripts)
     end

     action apt_scan
         axis 0              // axis to move

     end
