Saelig announces QuantAsylum QA403 24-Bit audio analyser

▤ Summary

The QA403 extends the functionality of its predecessor the QA402 with improved noise and distortion performance, in addition to a flatter response at band edges. The QA403 comes with a factory calibration in its flash memory, ensuring consistent unit-to-unit performance for reproducible results on additional analyzers. In a few clicks the user can obtain the frequency response, THD(+N), gain, SNR and more for a device-under test. The QA403 supports a REST interface, making it easy to automate measurements in most common languages from Python to C++ to Visual Basic to enable remote control. The software application reports both USB voltage and current, making it easy to know if a powered hub is needed.
