® Putting into Operation R&S RT‑Z1M Connecting the Adapter to the Oscilloscope 3 Putting into Operation Risk of shock hazard and injury Read and observe the instructions in Chapter 1, "Safety Information", on page 5 before using the adapter. During usage, the probe slightly heats up. Warming is normal behavior and not a sign of malfunction.
® Putting into Operation R&S RT‑Z1M Using the Adapter 3.2 Identification of Adapter and Probe When the R&S RT‑Z1M is connected to the oscilloscope, the oscilloscope recognizes the adapter and reads out the specific parameters from the data memory of the adapter.
® Putting into Operation R&S RT‑Z1M Using the Adapter These settings are: ● Offset ● Input coupling ● Lowpass filter (bandwidth) ● Self-alignment The gain or attenuation of the adapter is automatically set by the oscilloscope depend- ing on the vertical scale. 3.5.1 Offset Compensation The DC offset voltage is subtracted from the signal at the input of the R&S RT‑Z1M.
® Putting into Operation R&S RT‑Z1M Using the Adapter The bandwidth filter is part of the vertical settings of the channel to which the adapter is connected. For details, refer to the user manual of the Rohde & Schwarz oscilloscope. 3.5.4 Self-alignment The R&S RT‑Z1M has a self-alignment function.
® Typical Characteristics R&S RT‑Z1M Step Response 4 Typical Characteristics The R&S RT‑Z1M 1 MOhm adapter has several gain or attenuation modes. The mode of the adapter, and thus the gain or attenuation, depends on the vertical scale and is set automatically by the oscilloscope to achieve optimized system behavior.

® Typical Characteristics R&S RT‑Z1M Step Response ‑ Z1M (all 7 modes) Figure 4-2: Step response of the R&S RT The rise time of a system is inversely proportional to the bandwidth. The following approximation applies: rise The minimum measurable rise time of the whole setup also depends on the bandwidth of the probe connected to the R&S RT‑Z1M, and the bandwidth of the oscilloscope.
® Maintenance and Service R&S RT‑Z1M Cleaning 5 Maintenance and Service 5.1 Service Strategy Like all Rohde & Schwarz products, Rohde & Schwarz probes and adapters are of high quality and require only minimum service and repair. However, if service is needed, contact your Rohde &...
® Maintenance and Service R&S RT‑Z1M Discarding the Product To clean the exterior of the product, use a soft cloth moistened with either distilled water or isopropyl alcohol. Before using the product again, make sure to dry it com- pletely. 5.4 Calibration Interval The recommended calibration interval for R&S RT‑Z1M 1 MOhm adapter is two years.
® Functional Check R&S RT‑Z1M 6 Functional Check The functional check confirms the basic operation of the R&S RT‑Z1M 1 MOhm adapter and the R&S RT-ZP10 passive probe using simple measurement equipment. The functional check is not suitable to verify compliance with the specifications of the R&S RT‑Z1M 1 MOhm adapter, because the test results are influenced by the used oscilloscope.
