= Voltage to Frequency efficiency measurement of VCO =

Yesterday we measured this while the VCO seemed working properly.
Sugimoto-kun performed a linear fitting of this as shown in the attached figure.
The result is: 6.22(4) MHz/V or f = 6.22 * V + 43.6(3).
We might want to remeaure it after the strange behavior of the VCO is solved, though.
