® Putting into Operation R&S RT‑ZM Putting into Operation The probe is designed for usage with oscilloscopes that have a Rohde & Schwarz probe interface. Supported Rohde & Schwarz oscilloscopes are listed in the pro- be's data sheet. Read and observe the printed "Basic Safety Instructions" that are delivered with the probe.
® Putting into Operation R&S RT‑ZM Connecting the Probe to the Oscilloscope During usage, the probe slightly heats up. Warming is normal behavior and not a sign of malfunction. Connecting the Probe to the Oscilloscope 1. If your DUT is floating and not grounded, connect the DUT ground to the oscil- loscope ground before connecting any probe tip module to your DUT.
® Putting into Operation R&S RT‑ZM MultiMode Identification of the Probe When the probe is connected to the oscilloscope, the oscilloscope recognizes the probe and reads out the probe-specific parameters. The complete probe information is shown in the probe settings dialog. For more information, refer to the user manual of your oscilloscope.
