Assuming they are non counterfeit (not necessarily a valid assumption for items on eBay), how easy would they be to integrate into a box to make a stable reference? The LTZ1000A chip is about $50 new, but to make a stable reference you need quite expensive resistors, so a used 3458A reference is attractive. But I don't know if problems making low thermal EMF joints might totally ruin the potential performance. -- Dr. David Kirkby Ph.D CEng MIET Kirkby Microwave Ltd Registered office: Stokes Hall Lodge, Burnham Rd, Althorne, Essex, CM3 6DT, UK.
