The RF prober builds on the 300SA semi-automatic prober by adding RF probing capability. The frequency capability extends from the popular 40 GHz bandwidth to THz. Typically four micro-positioners are used, although more can be accommodated. The system can be turnkey based on your specifications, just the RF prober, or any situation in between. Moreover, the prober can be either an RF prober, a four-positioner DC prober, or a multi-site DC prober by swapping the platen.
