  • Page 23 ● Save the current settings (range, offset, coupling, channel name and channel color) as default. These settings are used at power-up of the R&S RT-ZISO when you use it with an unsupported oscilloscope. "Service" is restricted for use by service personnel.
  • Page 24 Connecting the probe receiver to the oscilloscope 3 Connecting the probe 3.1 Handling the probe The R&S RT-ZISO can withstand a moderate amount of physical and electrical stress. To avoid damage, treat the probe with care: ● Handle the probe by the probe receiver, probe head and probe box.
  • Page 25 ® Connecting the probe R&S RT-ZISO Connecting the probe receiver to the oscilloscope 3.2.1.1 Connecting the probe box and the probe receiver For connection, you need the scope connector cable. 1. Make sure that the oscilloscope is properly grounded. The probe receiver is grounded by the Rohde & Schwarz probe interface through the grounding of the oscilloscope.
