This signal analyzing equipment enables us to conduct a simultaneous measurement for frequency response generated from loudspeaker, SPL, Impedance, Fo, Ze, THD, Phase, polarity and C-MIC. It provides product inspection with optimum environment as frequency characteristics and sensitivity of built-in C-Microphone are controlled.
 It provides easy maintenance since the product can be installed in all types of computer system with PCI slots. All measuring items can be controlled by setting the criteria for Pass or Fail.
Special Feature:

1. A simultaneous measurement of Frequency Response(SPL), Impedance, Fo, Ze, THD, Phase, and
    Polarity provides fast results.
 2. High performance SNR>90dB.
 3. Sampling rate up to 96kHz
 4. Auto Calibration : Microphone. 
    Manual Calibration : Output voltage. 
 5. Pass, Fail settings and controls enabled.
 6. SPL Balance : SPL level deviation from Left and Right of stereo product can be controlled. 
    THD Method : Harmonics method can be selected to either IEEC or IEC.
 7. Computer-controlled operation Fast, hot plug USB interface.
 8. Measurement data is recorded as a file and the Avg, Min, Max, Cp, and Cpk of SPL, Fo, Ze, and THD(4point) can be 
     calculated (SPC).
 9. Can perform remote control through the Internet.
 10. Easy document printing in MS Word or Excel file (text format only) 
 11. Sound Card, MIC Pre-Amp, Conditioning Amp, Power Amp System control. 
 12. Built-in remote port which enables the connection into automated device.
    (Start, Pass, Fail, Test Run)
 13. Two input/output ports offer one-time inspection for stereo product. Separate input/output port for C-MIC inspection    enables the product inspection with built-in microphone.
