® Putting into operation R&S RT‑Z1M Connecting the buffer amplifier to the oscilloscope 3 Putting into operation Read and observe the instructions in Chapter 1, "Safety information", on page 5 before using the buffer amplifier. 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 buffer amplifier from the DUT ► To disconnect the buffer amplifier: a) Press and hold the release button (3). b) Pull the buffer amplifier away from the oscilloscope. 3.2 Identification of buffer amplifier and probe When the R&S RT‑Z1M is connected to the oscilloscope, the oscilloscope recognizes the buffer amplifier and reads out the specific parameters from the data memory of the buffer amplifier.
® Putting into operation R&S RT‑Z1M Using the buffer amplifier 3.5 Using the buffer amplifier 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 buffer amplifier is automatically set by the oscilloscope depending on the vertical scale.
® Putting into operation R&S RT‑Z1M Using the buffer amplifier 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 buffer amplifier is connected.
® Typical characteristics R&S RT‑Z1M Step response 4 Typical characteristics The R&S RT‑Z1M high-impedance buffer amplifier has several gain or attenuation modes. The mode of the buffer amplifier, and thus the gain or attenuation, depends on the vertical scale and is set automatically by the oscilloscope to achieve optimized sys- tem 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 test R&S RT‑Z1M 6 Functional test The functional test confirms the basic operation of the R&S RT‑Z1M high-impedance buffer amplifier and the R&S RT-ZP10 passive probe using simple measurement equipment. The functional test is not suitable to verify compliance with the specifications of the R&S RT‑Z1M high-impedance buffer amplifier, because the test results are influenced by the used oscilloscope.
