The capacitance at the crystal pins is in the range of 10 pF, and the impedance on this signal line is several megaohms. A typical passive probe has a capacitance in the range of 10 pF and an input impedance of about 10 MΩ. Both values are in the range of the oscillator characteristics and heavily influence the behavior of the crystal oscillators.
