Description

Most power benches need one dependable clamp for everyday current work. So the Rohde & Schwarz RT-ZC20 probe fills that role. It is an AC/DC clamp current probe. In fact, the R&S family page says its clamps read both DC and AC current. It covers 100 MHz and up to 30 A RMS at 0.1 V/A. Lost in HCM rents and sells it in Vietnam.

A 30 A clamp with a BNC output

This model connects to a BNC scope input. It also draws power from the separate R&S RT-ZA13 probe supply, so plan for that box on the bench. The small termination box carries DEMAG and ZERO ADJ controls for setup, as the manual explains. Then, at 0.1 V/A, a 10 A current reads as 1 V on screen.

Daily work in power and motor labs

A 30 A range covers a lot of ground. For instance, teams use a clamp like this for the jobs below.

Motor phase current in small drives and e-bikes.
Input current of power supplies and chargers.
Battery pack charge and discharge current.
Inrush when a product first powers up.

In each case the current stays inside 30 A RMS, while the edges stay well below 100 MHz. As a result, the Rohde & Schwarz RT-ZC20 probe covers most of the work a general power lab sees.

RT-ZC20 or RT-ZC20B

The two models share 100 MHz, 30 A RMS and 0.1 V/A. However, the RT-ZC20 uses BNC with the RT-ZA13 supply, while the RT-ZC20B uses the Rohde & Schwarz probe interface. So the choice depends on the scope inputs you already have.

Request the Rohde & Schwarz RT-ZC20 probe

A rental covers a test campaign or a customer audit, since both have an end date. On the other hand, buying makes sense when the clamp lives on your bench. In both cases, request a quote from Lost in HCM and say whether you need the RT-ZA13 supply too.
