The S-M90 Micropositioner is designed for RF probing. The positioner has one inch movements in all axes and captured cross-roller bearings to prevent accidentally moving the tip if bumped. An integral co-planarity adjustment provides for adjusting G-S-G tip planarity. S-M90 positioners are available with head configurations allowing the microwave head to be introduced from the front, rear, left or right side. The S-M90 is the most stable RF positioner available.
The S-M90 Micropositioner has been specifically engineered for the unique demands of high-frequency testing, rather than just modified from an existing DC design. Extended length ball and race bearings, captive leadscrews, and increased mass insure non-resonant performance to W-Band and beyond.
The S-M40 Micropositioner is also a robust RF probing tool with similar construction as the S-M90 with one difference: the inline X-Y-Z control knobs.
