Flexible FP160

FP120 Flexible Positioner

Flex Positioner FP120 is a versatile positioner for holding a variety of test probes, especially the widely used oscilloscope probes. Using the articulated arm for coarse positioning first and then controlling the fine adjustments with the XYZ stage and θ control, one can make good test measurements with reliable probe contact.
