Introduction:
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.
Special Feature:
1. Simultaneous measurement and assessment of Frequency Response (SPL), Impedance, Fo, Ze, THD, Phase, Polarity,
and Rub & Buzz.
2. High performance SNR>100dB.
3. Sampling rate up to 96kHz
4. Auto calibration : Microphone. Output voltage.
5. 4-stage pass/fail grade setting and management
6. Self-test supported for the hardware system
7. Computer-controlled operation Fast, hot plug USB interface.
8. Records measurement data in a file, calculate and conduct statistical processing (SPC) regarding the Avg, Min, Max, Cp,
and Cpk of SPL, Fo, Ze, THD (4-point), Rub & Buzz (4-point).
9. Can perform remote control through the Internet.
10. Easy document printing in MS Word or Excel file (text format only)
11. MIC Pre-Amp, Conditioning Amp, Power Amp System control. Remote control.
12. The comparative measurement can be made for the properties of several speakers. (Comparison)
13. The simulated measurement can be made for the changes of properties made in THD andRub&Buzz according to the
change of voltage given. (Simulation)
14. The existing standard microphone (B&K) can be used without any change, since the input terminal has the structure of standard LEMO 7-pin connector.
Option-01A:
Once connected to the automation system, outputs separate signals divided into 4 classes of pass or fail for all measurement items.
