• Change history (audit trail) Audit trails are records that chronologically catalog events (changes) to document who, when, and what changed in a configuration. In SonicTC, audit trails are created for both hardware configurations and processes and features. In some industries, such as medical device manufacturers, audit trails are mandatory (FDA). Standards such as IEC 62304 (Chapter 5.2) for software requirements and ISO 13485 for quality management also require the maintenance of audit trails. RTE’s audit software meets these requirements as standar
• Alerts (notifications) One of SonicTC’s greatest strengths lies in its automated operation as a testing system in networked industrial manufacturing (e.g., End of Life). To avoid operational delays, defined or automatically generated alarms can be triggered in the event of fault conditions. This allows the right decisions to be made quickly in critical situations without long delays, thus avoiding production downtimes and plant downtimes. Even in endurance test benches, which are used to test the service life of a product over extended periods, alarms for critical conditions ensure that unnecessary delays are avoided.
• Test procedures (test sequences) Another highlight of RTE’s testing software is the graphically configurable test sequences (configuration instead of programming). Engineers and technicians can use them to create test procedures, automate them, control devices/instruments, and synchronize with MES (Manufacturing Execution System) systems. Test sections can be configured in a structured manner in separate sequences and then called from higher-level sequences.
• Test sequence management For complete documentation and structured data storage of measurement and metadata, SonicTC provides comprehensive product/project management. Product management supports systematic data storage, including all explanatory data (metadata) and calculations, ensuring seamless traceability of the measurement and testing project at all times. Product management can also be used for variant management, helping to manage variant diversity. For example, products can be created in a structured manner, allowing the same feature configurations to be used for multiple variants. Product variables allow test sequences to be generalized and used for multiple product variants.

• Statistical process control The reliability of measuring equipment is ensured using standard measurement system analysis (MSA) methods. For this purpose, SonicTC offers, among other things, various metrics for measuring process capability (Cg, Cgk, Gage R&R) from the Six Sigma toolbox. • Process Capability Analysis The reliability of evaluation functions and characteristics, i.e., the process, is ensured using standard process capability analysis methods. For this purpose, SonicTC offers, among other things, various metrics from the Six Sigma toolbox: machine capability (Cm, Cmk), process performance index (Pp, Ppk), and process capability index (Cp, Cpk). • Data Distribution One of the most common requirements for statistical testing of an inspection system is that the acquired data is normally distributed. The basis for this is the probability diagram (Q-Q diagram), histogram, and box plot.
• Pareto analysis What are the most common test defects that occur in a process? Which features or associated problems have the greatest impact, and which are insignificant? Are resources being focused on the most common problems first? Pareto analysis is a tool that can be used to answer these questions. By aggregating a selection of test results, a histogram can be created that shows the most common problems, ordered by the percentage of defects. Filtering tools can be used to narrow analyses and determine, for example, how feature or process changes have altered the severity of certain problems.
• Defect analysis The Laney p’ chart is a control chart used to monitor the proportion of defective components while simultaneously correcting for over- and/or underdispersion in the data. The Laney p’ chart is similar to the conventional p’ chart. Both control charts monitor the proportion of defective components produced in the process.
• Correlation analysis Correlation analysis is a powerful tool in SonicTC. To optimize the analysis and evaluation of test objects and their measurement data, Pearson correlation can be used to determine the linear relationship between two or more characteristics and identify correlations. A correlation exists when there is a relationship between the characteristics. The correlation coefficient indicates the strength of the relationship and ranges from -1 to +1. The relationship does not have to be causal, as some properties of a system do not influence each other, or there is a stochastic, i.e., random, relationship between them.

• Transfer function The transfer function (FRF) is defined as the ratio of the response (output signal), i.e., acceleration, velocity, or displacement, to the excitation force (input signal), which serves as a reference. When constructing an averaged FRF, coherence can provide an indication of FRF quality. Estimation methods (H1, H2, Hv) are used to account for noise in the measurements.
• Order analysis Testing rotating or cyclically moving machines requires special testing procedures. Rotation-induced vibrations can be analyzed using order analysis.
• Modulation analysis Testing rotating or cyclically moving machines requires special testing methods. Modulation analysis analyzes modulated vibrations and noise, as well as their non-stationary components.
