I've got two different, but not totally unrelated questions.
1) Does anyone know what is the power consumption of the 3458A reference
board? I was thinking of getting one, boxing it up with a battery, that
allowed it to keep running without mains power. I would like to know the
energy storage the batteries would need to keep it running for 2 days.
2) Would there be any point fitting a similar board, with an LTZ1000A in a
3457A 6.5 digit meter? Would it be practical? I wonder if the drift on the
3457A's reference is significant, and so a LTZ1000A would be a worthwhile
upgrade. Or is the main drift not the voltage reference, and so such an
"upgrade" would be a total waste of time/money?
