Signatone S-M90 RF Micropositioner, DC–110 GHz

Designed for a Variety of Probing Applications

Features / Applications

Signatone offers an extensive line of Micropositioners to address virtually every probing and measurement

application, ranging from the very simple to the highly complex sub-micron high-resolution positioners.

The S-M90 stable 4-axis Micropositioner

For RF probe heads, High power probe heads, 4-point resistivity probe heads, Wedge cards, glass slides for material handling and a variety of other uses.

The smooth motion of the X-Y & Z knobs (at 90°) along with the micrometer driven planarization knob makes the S-M90 one of the most general-purpose positioners in the RF and High-power probing markets.
