Description
A passive probe is only as good as the parts at its tip. The Rohde & Schwarz RT-ZA1 kit is an accessory kit for R&S passive voltage probes with a 2.5 mm tip style. In plain terms, it holds the adapters, ground contacts, caps and coding rings that clip onto the probe front end, so one probe can reach many kinds of test points.
Probes that take the RT-ZA1
Rohde & Schwarz lists four compatible models: the RT-ZP10, RTM-ZP10, RT-ZP11 and RT-ZP1X. All of them are passive voltage probes, and all use the 2.5 mm tip. So if your bench runs one of these probes, this kit fits its front end. However, other probe families use other tip sizes, so check the probe label before you order.
What the kit holds
The R&S listing names BNC and dual adapters, ground contacts, IC caps, tips, a hook and coding rings. It also lists a 15 cm ground lead. In addition, the IC caps come in five pitches: 0.5, 0.65, 0.8, 1.0 and 1.27 mm. The R&S product photo shows a ground lead with an alligator clip, a sprung hook, a BNC adapter, ground springs, colored caps, rings and a tube of spare tips.
- IC caps let a probe tip sit on one fine-pitch IC pin without shorting its neighbor.
- Ground springs give a very short ground path for fast edges.
- The BNC adapter lets the probe read a BNC test port directly.
- Coding rings mark which probe feeds which scope channel.
Where a spare Rohde & Schwarz RT-ZA1 kit pays off
Small tip parts go missing fast on a busy line. For example, a ground spring drops into a fixture, or an IC cap cracks during a board debug. Then a spare kit keeps the probe in service instead of on a shelf. It also helps when a lab adds new passive probes and wants the full set of contacts for each one.
