What's New in dB-Lab 212.805 - QC 7.8

New: Minor dB-Lab Update

A new minor software update for the KLIPPEL Analyzer System is now available, featuring a new module that marks the next step in the identification of small and large signal lumped parameters - The Fast Large Signal Identification Professional (FLSI Pro). The new update also includes significant revisions and extended analysis capabilities for R&D modules such as KLIPPEL Endurance Test (KET) and Near Field Scanner (NFS) as well as optimizations for the QC products Sound Pressure (SPL) and Spectrum Analysis (SAN). The update is free of charge for all users running dB-Lab 212 or QC7.

The update features the pre-release of the Fast Large Signal Identification Professional (FLSI Pro) module, a groundbreaking tool for more accurate and efficient identification of small and large signal lumped parameters of electrodynamic speakers. By combining the previously separate measurements for small (LPM) and large signal parameters (LSI3) into a single measurement, FLSI Pro enables a streamlined workflow.

Key features in the FLSI Pro module include:

• Enhanced Speaker Model with New Nonlinearities: The extended model includes new nonlinearities, such as frequency-dependent inductance nonlinearity curves, port nonlinearity distortion components and effective surface area S_d(x) nonlinearity distortion components, as well as an extended linear model (e.g., inductance, creep behavior). This improves the accuracy of measurements and allows for a more detailed representation of the loudspeaker behavior.
• Nonlinear Distortion Visualization: Nonlinear distortion components are calculated and visualized as single relative distortion values and spectra, enabling a quick identification of the dominant causes of distortion, and providing valuable insights for design and development decisions.
• Unified Automatic Small and Large Signal Measurement: The new module merges small and large signal measurements into a single process, eliminating the manual import of results, thereby accelerating testing and increasing workflow efficiency. The measurement settings of the linear and nonlinear parameter measurements are determined fully automatically.
• Enhanced Protection Limits: Users can now set a maximum allowed voice coil displacement X_target, measured by a laser sensor, and activate a Rub & Buzz distortion limit, ensuring transducer protection from overload.
• Minimum Measurement Time: The FLSI Pro module reduces the test time significantly. A full measurement including thermal parameters usually takes less than 3 minutes. Multiple loudspeakers of the same type can be measured in less than a minute per unit, using settings from previous FLSI measurements.
• Thermal Parameter Identification: The FLSI Pro module identifies thermal parameters, which help to estimate the power handling capabilities of electrodynamic transducers.

In addition to the new FLSI Pro module, this update also introduces significant improvements to the KLIPPEL Endurance Test (KET):

• Laser Measurement supported: KET now supports laser measurements to monitor peak-to-peak excursion and instantaneous DC coil position, using the new plug-and-play software for integrating Keyence laser sensors. This development enhances the monitoring of long-term testing voltage, current, power, and temperature. More information is in the detailed application note AN83.
• Improved Temperature Monitoring:
• The update provides very low-frequency pilot tones to the test signal for endurance tests, significantly improving the precision of temperature monitoring. These tones minimize errors caused by intermodulation distortion. Smooth, fast temperature monitoring is now available across all supported amplifier models, including Powersoft Mezzo and Unica series..
• Calibration Tools: The new version enables local or certified laboratory calibration of amplifier gains and voltage/current readings, ensuring accurate and traceable measurements. Detailed software tools and instructions are provided to streamline the calibration process.
