To convert that to the noise measured on the actual beat-note, it must be rescaled with the following formula:
  
 ''D2-135 Phase-Noise Floor = -213 + 20Log(N) + 10Log(F<sub>REF</sub>)'' ''D2-135 Phase-Noise Floor = -213 + 20Log(N) + 10Log(F<sub>REF</sub>)''
  
  
-where N is the value of the divider and F<sub>REF</sub> is the reference frequency as measured in Hz.
