SM40RF & Microwave micropositioner

The SM40 micropositioner is specifically designed for RF probing, it has one inch translation capabilities in all axes and a cross-roller bearings to prevent accidentally moving the tip if bumped.

- Accepts all types of coplanar RF probes.
- Perfectly stable with screw-lock fixation on the platen (optional magnetic base).
- An integral co-planarity adjustment provides for adjusting multicontact planarities (GS, GSG, GSGSG configurations).
- It is available with various head configurations allowing the microwave head to be introduced from the front, rear.
