The 20660 is isolated near the needle/probe for less capacitance. The clamping collet has three slots for holding the needle at 60, 75, 180 degrees. It is connected to 3 feet of 50 ohm RG 174 coaxial cable ended in a BNC male connector and can be mounted on any of our translation stages.

The 20660-T Triax version is isolated near the needle/probe for less capacitance and is the same physical size as the Coax version. The clamping collet has three slots for holding the needle at 60, 75, 180 degrees. It is connected to 3 feet of 50 ohm triax cable with a 3 lug triax male connector.

Positioners can be damaged by placing too much load or using them as a vice.
