Hi Guys and Gals i'm new to all this electronic stuff and this maybe a simple question....but i would like some help if I may ask.
ok here is what i need to build.
i would like to make a interface to a Data Acquisition Unit that will provide a stepping mv source to the DAU for addressing checks.
I was thinking of using a 9v battery as a voltage source (could also be an external DC power supple source) and using a bank of resistors (could also be variable resistors) to divide the voltage over 18 channels to a 37 pin cannon type connector. also there is a requirement to be able to induce a 30V peak CMV at random while the other lines are floating.
can some one advise me on how i can build this interface box...I have no idea. also is there a way to make this programmable ?
best regards
Carl
