Loud Speaker에서 발생하는 Frequency Response, SPL, Impedance, Fo, Ze, THD, Phase, Polarity, Rub&Buzz를
동시에 측정 할 수 있는 신호 분석 장비 입니다. 기존의 청각 검사에 의해 판별하던 이상음(Rub&Buzz) 검사를 고조파
신호 분석을 통하여 보다 정확하게 검사. 판별 할 수 있습니다. 여기에 적용된 신호분석 알고리즘은 혁신적이고 새로운
방법으로 미세한 Rub&Buzz를 감지해 낼 수 있습니다. 4단계에 걸친 불량 단계 설정으로 보다 세밀한 판정이 가능합니다.
입력과 출력 단자는 2개로 구성되어 있습니다.

1. Frequency Response (SPL), Impedance, Fo, Ze, THD, Phase, Polarity, Rub&Buzz를 동시에 측정 및 판정.
2. High performance SNR>100dB.
3. Sampling rate up to 48kHz
4. Auto calibration : Microphone. Output voltage.
5. 합격, 불합격 등급을 4단계로 설정, 관리 가능
6. Hardware System Self Test 가능.
7. Computer-controlled operation Fast, hot plug USB interface.
8. 측정 Data는 File에 기록되며 SPL, Fo, Ze, THD(4point), Rub & Buzz(4point)의 Avg, Min, Max, Cp, Cpk 값의 연산
및 통계 처리(SPC).
9. 인터넷을 통한 원격 제어 가능.
10. Word 또는 Excel(Text Format)로의 쉬운 문서 출력
11. MIC Pre-Amp, Conditioning Amp, Power Amp System control. Remote control.
12. 2개로 구성된 입력과 출력 단자는 측정이 동시에 이루어 지므로 Stereo로 구성된 제품도 한번의 측정으로 분석이
가능합니다.
