[DSP-10] Z3801A Tuning range

[3.1415926535897932384626433832795]

Hi All,

I believe that the Z3801A has a HP 10811 oscillator built in that does not
have a tuning screw. This is to not require user tuning. The electronic
tuning range has been increased to allow electronic tuning over the age of
the oscillator. I just checked the tuning voltage using the command  below
and I am sitting at 42%. The useful range is +/- 100%. Does this mean that I
have 60% to go before I have to throw this thing in the garbage? Just a
thought. Here is the command to check it:

DIAG:ROSC:EFC?
