[time-nuts] Fw: Rb Oscillator - rather fundamental question

[EWKehren at aol.com]

The HP 5062C is not a "Primary Standard", and that is why it is called a  
"Reference" because it uses a different transition of Cesium 133 with the  
frequency of 9192.631,774,3 MHz which does not meet the definition of a second 
 and resulted in a relative short product life even though modified to run 
with a  FTS tube and "Standard Frequency" makes it a grate Frequency  
Standard.
