Internals

An initial 8 MΩ : 2 MΩ divider drives a dual JFET (source follower + current source), a PNP emitter follower and finally an NPN emitter follower as a cable driver. These stages use SMD components located in the probe tip. The probe control box at the end of the coax only contains a ±7 V regulator, a switchable 50 Ω terminator, and the offset potentiometers that supply ±15 V to the bottom of the input divider. There is no input protection apart from the divider.

Compatible probe tip to coaxial adapters

While the probe body is wider than regular miniature modular probes, some accessories are compatible. The manual lists the following adapters in particular:
