This uses the same active device as the first probe, a BF998 FET, but several components are different. The signal might be low and the probe might interfere, so you should build a FET-preamplifier to your probe. Since the BF998 has useful gain around 1 GHz or more, parasitic oscillation is always a concern, and yes, a source follower can oscillate as it has power gain. Short-channel transistor with high S / C quality factor; For low-noise, gain-controlled input.
