Rohde & Schwarz ZNrun software

Rohde & Schwarz ZNrun software assists users in configuring measurements specifically for multiport DUTs using Rohde & Schwarz VNAs. The user selects the VNA and any additional test equipment - eg, an R&S ZNB vector network analyser and an R&S ZN-Z84 switch matrix - and sets the parameters to be measured on the DUT. Based on this information, the software takes over communications with the test equipment, makes all of the settings and executes and controls the test sequence. This procedure simplifies in particular the time-consuming characterisation of multiport components.

The product also supports the user during calibration, which is especially time consuming and complex in the case of multiport applications. The software shows exactly which test port should be connected to which calibration standard or port on a calibration unit. Moreover, each port can be colour coded or assigned a user-specific label to make it easier to identify. It is also possible to repeat individual calibration steps.

The software runs on an external PC. A graphical user interface is available for easy configuration of complex test scenarios. In addition to VNAs, switch matrices and DUTs, the software also enables the integration of external devices such as power supplies into the test setup by using plug-ins. The configured test scenarios are independent of the test equipment used. If a test setup is modified, the user merely selects the new test equipment in the software - there is no need to completely redefine the test.

For daily use in the production line the R&S ZNrun GUI offers a simplified view, with a straightforward pass/fail result display for every test. The software also indicates how many of the DUTs passed the tests and how many failed.
