This signal analyzing equipment enables us to conduct a simultaneous measurement for frequency response generated from loud speaker, SPL, impedance, Fo, Ze, THD, Phase, polarity, and Rub & Buzz. High-frequency signal analysis offers even more accurate testing and identification of Rub&Buzz than existing hearing tests. The algorithm of signal analysis applied to this device allows to detect even minute Rub & Buzz due to its innovative and new method. The 4-stage defect setting enables even more in-depth assessment.
Features
• Linear and Log(Octave) System analysis.
• Impedance – Voltage and current measurement for loudspeakers.
• High performance SNR>100dB
• 24Bit Sampling frequency up to 48kHz.
• Computer-controlled operation Fast, hot plug USB interface.
• Easy reporting using Microsoft® Word or Excel (Text Format)
• Calibration of input and output signals in commonly used units
• Simple Constitution: Audio Analyzer has built-in Audio Amplifier and Conditioning Amplifier.
• A simultaneous measurement of Frequency Response, SPL, Harmonics Impedance, Fo, Ze, THD, Phase, Polarity, and Rub&Buzz provides fast results
• The control line is divided into four classes for grading control.
• Can perform Self Test to check condition of hardware system.
• Measurement data is recorded as a file and the Avg, Min, Max, Cp, and Cpk of SPL, Fo, Ze, THD(4point), and Rub&Buzz(4point) can be calculated (SPC).
• Can perform remote control through the Internet.
• Can connect to an automation system by installing Option-01A.
• If the results show “Fail” due to an external noise (shock, etc) during the measurement, measurement is run automatically again.
• Stereo product can be effectively inspected since CH-A and CH-B are measured at the same time.
