Virtually all of the adjustable calibrators from Fluke, Valhalla, and others
do a PWM to precision voltage conversion.

Joe,
Loss of accuracy in the conversion process is probably the biggest reason.
It's also less complex to build the voltage standard to a higher degree of
accuracy and stability than to build an accurate, stable frequency
standard AND an accurate, stable V to F converter.

I imagine that this has been discussed before, but I didn't see anything
in
the archives. Long before my recent weakness and ordering of that voltage
standard on ebay, I had thought about using a voltage to frequency
converter.
Since it is relatively easy and inexpensive to have a very accurate
frequency standard at home, I wondered how difficult would it be to use
that standard to create an accurate voltage standard.
Some Googling didn't turn up much along these lines. Since this method
apparently isn't being used, there must be some reason. Can anyone
enlighten me?
