Jean-Louis, My DC standards are a Fluke 731B and Fluke 335A DC Voltage Standards and an EDC CR103 DC Current and Voltage Standard.
My resistance standards consist of a collection of Leeds and Northrup type standard resistors as well as a collection of General Radio Decade Resistance boxes that will get me up into the MegOhm range. However, AC promises to be a problem. I guess I will try using a signal generator and an amplifier to see what output level and stability I can achieve. But still, what frequency? 60 Hz? 1 kHz?

The stability is not high enough to be useful! Have a look to http://www.on4jln.be/infos/getfile?file=515A-OM.pdf, it is the Fluke 515A, to learn how they dealt with that problem. If your 10V is good you will get better results too. And it needs to be very good to calibrate the 7081! Stability is more important than everything else and that is the problem. Have a good day.
