[volt-nuts] "*WAY* too expensive for even Keysight to redesign"

Overall,  I agree that a voltmeter such as the 3458A may not be cost 
effective any more to redesign all functions from the ground up. 

Consider that Fluke has re-released the Datron 1281 as its 8508 voltmeter. 
A quick view of the specs shows that Fluke has made marginal improvements 
to the DC volt side, good improvements to the DC current and Resistance 
side, but largely left the AC volt and AC current performance alone. Never 
mind the 8508A 20A current range, which seems to me like a bolted on 

Fluke has added functionality for PRT measurements, and replaced the vacuum 
display with an LCD. Does anyone want to check if Fluke kept the 68000 
processor and its architecture ?
