[time-nuts] Questions about HP 5370B

[Javier Herrero]

  Hello,

My 1986 HP catalog do not show a high stability oscillator as an option 
for the 5370B, and from the time base aging effects graphs it appears to 
have a 1E-8/month oscillator. My 1996 catalog also do not shown this as 
an option, but the specs for the 5370B are so sparse that they even do 
not mention anything about acuraccy.

Regards,

Javier
