[time-nuts] Line Voltage frequency Interface morphed to batteries

[Peter Gottlieb]

Oh, yeah, about the line interface for measurement...

I hooked up a 47k resistor from line to the 50 ohm input of my 5334B and it 
"just worked."  I am watching the 60 Hz drift all around as I type this 
(although not all that far, seems to be holding within 0.01 Hz tonight).
