3458A METCAL Proceedure

Has anyone come up with a METCAL procedure to test a 3458A with a 5720A Calibrator, Function Generator, and Standard Resisters?

3458’s are remarkably accurate and using resistors/shunts to try to drill down to the microvolt AC level uncertainties isn’t a task that’ll produce repeatable results unless you have the controls of a primary standards lab. I’d advise against trying to calibrate a 3458 in this fashion.

We do our options 1 in house using the Fluke5720A, HP 33120A and we use Fluke 742A in correlation with a 3458A-002 to justify the current readings. I was hoping someone has already done a similar procedure as apposed to start from scratch.
