Description
A high-end scope and a general-purpose probe do not always speak the same language. The Rohde & Schwarz RT-Z1M adapter bridges that gap on R&S RTP oscilloscopes. In R&S terms, it is a high-impedance buffer amplifier, so “adapter” on this page means that buffer module. Through it, the RTP can also take passive, current and high-voltage probes.

Three jobs in one module
- Buffers the probe signal with a high input impedance.
- Connects passive, current and high-voltage probes.
- Adds an integrated high-precision DC voltmeter.
R&S also includes the RT-ZP10, a 500 MHz, 10:1 passive probe. So you can start measuring with a standard probe as soon as the adapter arrives.
Why RTP users ask for it
Many lab tasks still call for a classic probe, even on a top-class scope. For example, an engineer may need to check a slow supply rail next to a fast data line. With the Rohde & Schwarz RT-Z1M adapter, both jobs stay on one RTP. In addition, the built-in DC voltmeter lets you read a DC level without a separate meter on the bench.
What the photo shows
The R&S product photo shows a white module with a BNC socket at one end and a grey release lever on top. In addition, its label carries the R&S logo, the model name, the text 1 MOhm Adapter and a maximum input voltage warning. Follow that label, the manufacturer’s manual and ratings whenever you connect a probe.
Ordering the Rohde & Schwarz RT-Z1M adapter
Lost in HCM rents the RT-Z1M for project work on an RTP and sells it for permanent setups. First, confirm your RTP model. Then request a quote from Lost in HCM and list the probes you plan to attach. More choices sit under oscilloscope probes, and you can contact SMK Vietnam with questions. The R&S probe accessories page lists it under order number 1337.9200.02.
RT-Z1M adapter FAQ
Which oscilloscopes accept the RT-Z1M?
R&S lists the RTP oscilloscopes, so confirm your exact model with Lost in HCM.
Does it come with a probe?
Yes. R&S includes the RT-ZP10 passive probe, rated 500 MHz and 10:1. Check the full contents in your quote.
Can I attach a current probe?
R&S says it connects passive, current and high-voltage probes. Still, check your exact probe model before you order.
