Hi, maybe [AD]? I need to buy a precision RLC bridge at a resonable price. I am thinking to 0.02% to 0.1% basic accuracy. What do you know about old GenRad 1658 or GenRad 1689 models ? thank you, Vasile -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
