[time-nuts] HP 5335A Question

[Richard Mogford]

I have an HP 5335A and I am measuring the output of a Suzler 2.5.  I 
have a GPSDO 10 MHz input into the back of the 5335A.

There is mention in the manual that the counter can display 11 or 12 
digits (in addition to the two Exponent digits).  I presently have it 
displaying nine digits.

Does anyone have one of these and could help me figure out how to get 12 
digits displayed?  The manual is not very helpful here.
