1) make the 1000V smaller and less powerful ( transformer ?, current limit resistor?) 2) maybe convert it to DC 2a) maybe other conditioning, i dont know frequenct or even the nature of the signal 3) read the small weak value with an ADC 4) connect ADC output (small voltage binary image) to emc :) you can see #4 is very far from #1 you need to test each step before going to next step there are lots of internet resources about how to observe voltage and current wit computers best of luck, tomp ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
