DC, RF and Optical Probe Positioning for Highest Accuracy Measurements

FormFactor offers a wide variety of manual and motorized probe positioners for any application from DC to terahertz measurements and beyond.

The MVG-Orbit/FR performance series has recently been expanded to include medium-duty, dual-axes positioners: the new AL-438X series. Thanks to their low profile design and advanced drive mechanism, these symmetrical AZ/EL positioners ensure accurate, balanced rotation, and

Their rugged yet straight-forward construction ensures maximum reliability and trouble-free operation, yielding the best size and weight / performance ratio. This particular series provides a counter weight option which improves overall system stability and accuracy while allowing for higher DUT loads. A large variety of options is available for this ORBIT/FR standard product family.

MVG medium duty azimuth positioners provide accurate rotation, velocity, and direction and offer turntable diameters up to 30 in (686 mm). Rugged yet simple construction ensures maximum reliability and trouble-free operation.
