Keysight 1 and 2 Arm Probe Positioners The N2784A single arm probe positioner (134-6160) and N2785A 2-arm probe positioner (134-6162) provide quick and stable X-Y positioning with only a “lift and drop” motion to put the probe in place for PC boards and devices that require hands-free probing. This probe holder also employs a weight stabilization technique to keep constant pressure at the probing point so that the probe tip stays in position even when the target board is shaken. These probe positioners are compatible with most Keysight scope probes including InfiniiMax single-ended or differential browser probes, as well as the scope probes from other vendors. Features and Benefits • Easy-to-manipulate probe arm for hands-free browsing • One articulated arm with hi-mass base • Quick and stable XY positioning • Weight stabilization technique in probe holder keeps constant pressure at the probing point • Compatible with most Keysight and other vendor’s scope probes
