Klippel Supports MegaSig U980 Bluetooth Interface for R&D and QC Line Testing

December 16 2019, 01:10
Klippel now officially distributes and supports the MegaSig U980 professional Bluetooth interface. Together with the Klippel Analyzer System, this USB-controlled, analog signal converter supports reliable testing of any audio device enabled with Bluetooth wireless technology such as portable speakers, wireless headsets, and true wireless earbuds with a fully integrated solution for both lab and end-of-line context. 

The MegaSig U980 Bluetooth v4.0/4.2 wireless converter is just one of the many great value products available from the Chinese manufacturer and this model is equipped with an analog and USB audio interface, supporting stand-alone and Windows Bluetooth applications. This solution supports fast pairing by address, offers automated pairing for production line testing and supports all SBC, aptX, aptX Low Latency, aptX HD, CVSD, and mSBC codecs. With this set of features, Bluetooth audio devices such as portable speakers, wireless headphones, and true wireless earbuds can be reliably tested with a fully integrated solution in both QC & R&D contexts. 

The External Devices (EXD) Bluetooth software integration - allowing integration of 3rd party control and measurement instruments - provides fast, automatic, name- or address-based pairing as well as broad codec support in both A2DP (SBC, aptX, aptX HD & LL) and HFP (CVSD, mSBC) audio profiles. 

When special testing applications or complex integrated tests of audio systems require controlling and obtaining data from stand-alone instrumentation equipment such as digital multimeters, programmable power supplies or switching devices, the External Devices (EXD) optional module for the Klippel QC Framework extends the capabilities of the QC System by providing a communication interface for GPIB compliant devices. 
The Klippel Analyzer System is a comprehensive testing tool from lab to production and can now be complemented with the MegaSig U980 professional Bluetooth interface. The image shows an example of a closed-loop setup for a Bluetooth speaker with a built-in microphone.
Complex sequences can be set up quickly with simple scripting while more simple tasks can be handled with presets. Fully integrated into QC tests, this module provides limit handling and data logging for externally acquired measurement data. In addition to GPIB handling, the EXD provides many other interfaces for user interaction, control and data acquisition. This includes Windows Bluetooth Radio control for automated testing of Bluetooth enabled devices (pairing, profile and volume control).

dB-Lab Version 210
Meanwhile, Klippel continues to expand its software dB-Lab version 210, the company's unified framework for R&D and QC audio testing, diagnostics and simulation, now receiving a minor update. It includes bugfixes and minor feature updates for released modules and beta test products like the Live Audio Analyzer (LAA). This update is free of charge for any dB-Lab 210 user. More information about the new software update can be found on the Klippel website and also in the “What’s new in dB-Lab 210 – QC 6.4” information sheet.

Visitors to the Klippel website might also want to check the AN 73 QC Headphone Testing application note, which has also been revised with the latest Bluetooth testing features. Many more application notes are available on the Klippel website.
