The OP may like to look at the Keithley range of gear. I have a 2400 Sourcemeter and a 2700 DVM, but I suspect these are way over spec'd for what is required. Both items can be GPIB driven, and have more digits of accuracy than anyone except a calibration lab is normally likely to need. Keithley are always worth a look for an out of the ordinary instrument as they have purposely set out to fill niche gaps in the instrument market that the "big guys" don't work at. Check with their rep anyway and see what they can give as discounts, especially if you are looking at getting enough to fit out a lab. I suspect you could probably get a clutch of 2700 series machines for very reasonable price. http://www.keithley.com/main.jsp -- http://www.piclist.com#nomail Going offline?
