Description

Bandwidth costs money, so match it to the signal. The Rohde & Schwarz RT-ZC15B probe offers 50 MHz and up to 30 A RMS at 0.1 V/A. It is a clamp current probe. Moreover, Rohde & Schwarz describes its scope clamps as non-intrusive tools for DC and AC current. It connects through the Rohde & Schwarz probe interface. Lost in HCM rents and sells it in Vietnam.

How much bandwidth do you need?

A probe only needs to follow the fastest edge in your circuit. Many motor drives, battery systems and mains-side stages switch well below the speed that would call for 100 MHz. In that case, the RT-ZC15B gives the same 30 A range as the RT-ZC20B, with half the bandwidth. So you pay for the speed you use and nothing more. Besides, 50 MHz still shows plenty of switching detail on many drive and charger stages.

Work that fits the Rohde & Schwarz RT-ZC15B probe

Phase current in BLDC and stepper motor drives.
Battery management and pack current checks.
Automotive actuators, pumps and heaters.
Power factor correction stages on the mains side.

On the other hand, fast GaN or SiC edges may need more headroom. Then the 100 MHz RT-ZC20B is the better pick.

Connection and setup

The listing names the Rohde & Schwarz probe interface as the connection, so check your scope first. After that, degauss and zero the clamp as the Rohde & Schwarz manual explains. Also set the channel to 0.1 V/A, so 5 A shows as 0.5 V.

Quotes for the Rohde & Schwarz RT-ZC15B probe

A rental suits a field trial, a supplier audit or a short R&D peak. Meanwhile, a production test cell may want a permanent unit.
