Rohde & Schwarz RT-ZAP Positioner, 3D Probe Holder with 200 mm Span and 15 mm Clamping Range

Description

Holding a probe tip still on a tiny pad for minutes at a time is hard work for any hand. The Rohde & Schwarz RT-ZAP positioner takes over that job. Here, “positioner” means a 3D probe positioner: a round base, an articulated arm and a clamp that holds the probe. R&S lists it for all R&S oscilloscope probes.

Key figures

Hands-free probing

The Rohde & Schwarz RT-ZAP positioner frees both hands, so you can work the scope while the tip stays put. That matters during long captures, such as a slow power-up sequence or a rare glitch hunt. It also helps when two probes must touch nearby points at once. In addition, a fixed tip gives repeatable contact, so you see steadier results from run to run.

Setting up the Rohde & Schwarz RT-ZAP positioner

First, place the base close to the board. Next, release the central knob and swing the arm into position. Then fit the probe in the clamp and tighten the knob again. R&S gives a 15 mm clamping range for the probe body, while the 200 mm span sets how far the arm can reach.

The R&S product photo shows a black round base, a two-part arm with a star knob at the joint, and a metal fork clamp at the far end.
