WL-210 RF / Microwave Probe Station

The Signatone analytical probe station is recognized as the performance / value leader in the microprobing market. The WaveLink Series extends this expertise into the RF & MW sector, historically subjugated by more expensive alternatives.

While RF & MW probing have been classified by some as a difficult, mysterious application, this is no longer the case. Any modern probe station precise enough to contact a sub-micron line is certainly stable enough to hit a 100m pad with a 50m RF probe. What's more, in the past decade, we have seen improved network analyzers having more stability, accuracy, and ease of use. Signatone believes your probe station should be equal to the application requirements.

Building on the proven CheckMate architecture, and in consultations with our installed base of RF technologists, Signatone has incorporated many features into the WaveLink Series unique to the world of VNA's and coplanar probes.

WL-210E Probe Station

A significant portion of leading-edge probing applications require that the wafer be enclosed in an environmental chamber, either for electrical shielding or to provide frost-free probing.

Traditional approaches use a variety of methods to provide this functionality, but they all share one significant limitation; mechanical interference between the stage and the enclosure. This makes ultra-fine positioning of the wafer extremely difficult, if not impossible. By eliminating the sliding plates commonly used to close off the bottom of the enclosure, and utilizing remote motor control, Signatone E-Manual stations give the best of both worlds; mechanical isolation and sub-µ positioning

A 10:1 vernier switch solves the problem inherent in conventional manual leadscrew designs by providing rapid motion for large moves and precise control for final positioning of the wafer.

Like all Signatone probe stations, the WL-210E is fully upgradeable to support future probing requirements, including full-range thermal and semi-automatic configurations.
