® Putting into operation R&S RT‑Z1M Connecting the adapter to the oscilloscope 3 Putting into operation Read and observe the instructions in Chapter 1, "Safety information", on page 5 before using the adapter. For your safety, follow the safety instructions delivered with your Rohde & Schwarz oscilloscope and probe, and the instructions given in the manuals of your measure- ment equipment.
® Putting into operation R&S RT‑Z1M Disconnecting the adapter from the DUT ► To disconnect the adapter: a) Press and hold the release button (3). b) Pull the adapter away from the oscilloscope. 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 3.5 Using the adapter All settings of the R&S RT‑Z1M are adjusted on the oscilloscope. 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.
® Putting into operation R&S RT‑Z1M Using the adapter 3.5.3 Analog bandwidth The R&S RT‑Z1M features two lowpass filters of 200 MHz and 20 MHz. The filters reduce bandwidth and thus noise during the measurement. The bandwidth filter is part of the vertical settings of the channel to which the adapter is connected.
® 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.

® 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.
