The R&S® Remote Service Tool can communicate with the R&S® CMU via the GPIB (IEEE 488) or a RS-232 interface. To ensure fast transmission, it is recommended to use the GPIB interface, connecting the GPIB cable to the IEEE 488 / IEC 625 connector on the rear panel of the instrument.
Note: The GPIB settings of the Remote Service Tool and of the R&S® CMU must be the same. Refer to section Connecting a Controller on p. to learn how to configure the R&S® CMU’s GPIB settings.
1. Connect the GPIB cable to the IEEE 488 / IEC 625 connector on the rear panel of the instrument.
2. Start the Remote Service Tool.
3. Click the Options menu and make sure that Use GPIB is selected.
4. Click Options – GPIB Options and check that the Board Index and Primary Address settings are equal to the R&S® CMU configuration (CMU default settings: board index GPIB0, primary address 20).
