Hi Forrest: You might look for a used HP/Agilent Mobil Communications DC source, like t= he 66311A, see: http://www.prc68.com/I/HP66311A.html Tthink of it as a sampling scope combined with a power supply. They sell software that allows you to display scope type traces on a PC, bu= t the programming info is freely available. From the front panel you can select things like average, max, min etc. Have Fun, Brooke Clarke http://www.PRC68.com http://www.end2partygovernment.com/2012Issues.html piclist-request@mit.edu wrote: > [EE] Current/Wattage Monitor for low current devices --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
