The Keysight N2787A is a 3D probe positioner that delivers stable, precise positioning of oscilloscope probes across three dimensions. Its flexible articulating arm provides hands-free access to hard-to-reach test points on PCBs and assemblies, while fine adjustment knobs ensure repeatable probe contact during measurement. The universal probe holder accommodates a broad range of Keysight and third-party probes, making it an essential accessory for bench and production test environments.
