[Test-Equipment] AC voltage Standard

[Bill Abate]

I am trying to calibrate a FET VOM I recently got.  I have resistance 
standards and I have a DC voltage standard.  So I was able to check 
those scales.  But then I got stumped with the AC calibration.  I'm 
pretty sure I saw something in Ham radio, etc. that showed how to use a 
DC standard for AC but I can't find it again.  I have an article that 
shows a chopper  with a DC circuit as a scope calibrator but that is a 
square wave.  Anything for a sine wave that is not a two week project in 
itself?

Yes, I have DVM that I could use as a standard but that is a little 
lame.  Anything in HR, QST. etc.?
