VCXO measurements

Hi, I've measured how the 26 MHz VCXO changes frequency depending on the AFC DAC output. See the attached plots and the data file. Tapping point is between C132 and C210 (RITA Xout). On my 20 MHz scope it's 300 mVpp, but I'm hitting the bandwidth limit of the scope, the frequency counter says -0.03 V ...+0.02 V after a x10 probe (500mVpp). I'll put it in the fridge later on to check the temperature coefficient.
