The Keysight N2786A is a low-cost, easy-to-use X-Y axis probe holder for general-purpose probing applications. The two-legged positioner is designed to be easy to use - the positioner itself has no controls to position it in place. This positioner has three different sized apertures into which various sized probes can be placed. All of Keysight’s 2.5mm and 5mm passive probes such as N2870A-76A, 10073D, 10074D, etc., and most other passive probes in the market can be used with the N2786A positioner.
