[time-nuts] Input voltage for Zeeman on 5061A

[John Ackermann N8UR]

Anyone know how much voltage you need to drive the Zeeman input on the 
5061A?  I just tried to set mine and found that the maximum output from 
my 3325A (3V RMS) was barely enough to see any wiggling at all on the 
beam current meter  I have another generator that goes up to 6V and that 
got me a bit more, but even then only a few meter divisions between peak 
and dip.

Either I need a heftier generator (or maybe an impedance step-up), or 
we're back to the question of what is the right Zeeman frequency for an 
FTS tube in an HP chassis.

Thanks,

John
