Description
Cutting a trace to fit a shunt takes time, and it also changes the circuit you want to study. The Rohde & Schwarz RT-ZC10B probe skips that step. It is a clamp-on current probe with 10 MHz bandwidth, so you close the jaw around a conductor and read the current waveform on your oscilloscope.

Rohde & Schwarz describes its current probe family as a non-intrusive way to measure both DC and AC current. So one clamp can show a DC bias and the ripple riding on top of it.
Where a 10 MHz clamp fits
Ten megahertz suits the switching rates of many motor drives, inverters and industrial power supplies. For example, you can watch phase current in a servo drive while the firmware team tunes its control loop. You can also capture inrush when a contactor closes, or compare the current draw of two board revisions. Because the sensitivity is 0.01 V/A, a 10 A peak shows as 100 mV on screen, which keeps scaling simple.
Rohde & Schwarz RT-ZC10B probe or RT-ZC10?
On the Rohde & Schwarz site the two share the same bandwidth and current range. However, the connection differs. The RT-ZC10B plugs into the Rohde & Schwarz probe interface. By contrast, the manufacturer lists the RT-ZC10 with a BNC output and a separate RT-ZA13 power supply. So the B version keeps the bench tidier when your scope offers that interface.
Before you book it
Lost in HCM lists this probe as an accessory for the R&S RTM3000 family. Still, check the probe interface and firmware on your own oscilloscope first. Then send the scope model and serial number with your request. Lost in HCM can rent the probe for a test campaign or sell it for permanent use, and it also arranges service on request.
Care between jobs
Keep the jaw faces clean, because grit in the core gap can upset readings. Also store the cable in loose coils rather than tight bends. Above all, follow the manufacturer’s manual and ratings for every measurement.

RT-ZC10B FAQ
Does the RT-ZC10B need an external supply?
Rohde & Schwarz lists the RT-ZA13 supply for the RT-ZC10, not for this model. This one uses the probe interface instead. Confirm the setup for your scope with Lost in HCM.
How much current can it measure?
The manufacturer gives 150 A RMS as the maximum. Check peak and frequency limits in the manual before a test.
What is the order number?
The manufacturer order number is 1409.8210.02, and Lost in HCM confirms it in the quote.
