• Measure the ANC using the SG-5822B. (Option-01)
• You can check the ANC function of Headphone / Earphone.
• Frequency response characteristics of Unoccluded, Passive, Active, and Monitor modes can be measured.
• Regardless of wired or wireless products, ANC mode control and sensitivity
calibration can be performed automatically by adding the control protocol of the
ANC chip used in the product.
• Basic Pink Noise, Sine Sweep can be used as a measurement signal, and Pink
Noise and Sine Sweep signals can be corrected so that the frequency response
characteristics of the signal output from the Driver Speaker are flat.
• Since ANC Measurement and Continuous Sweep can be configured in a complex
Signal Path, it is possible to inspect all items (ANC calibration, measurement, SPL,
THD, Phase, Rub & Buzz, Blance, Polarity) by performing one inspection sequence.
✔ ANC measurement using B & K Anechoic Test Box (Type 4232)
✔ Applying a chamber that can be opened and closed automatically enables all calibration and measurement of earphone and headphone products.
Audio Analyzer SG-5822B
- Bluetooth Speaker / Earphone measurement system
Introduction :
SG-5822B is a measuring instrument that can inspect the finished Bluetooth Speaker / Earphone in real operation. By using the Chirp algorithm, the measurement stability of Bluetooth products with unstable synchronization is improved. In addition, stereo earphones and microphones for calls can be continuously inspected automatically while pairing and connecting with Bluetooth speakers and receivers automatically. Four measurement microphones can be connected and two channels are measured at a time. Measurement results can be communicated with external automation devices such as PLCs through the Communication Port. It can measure USB-C type earphone products.
You can test ANC (Active Noise Canceling) function of Headphone / Earphone. (Option-01)
With the EQVoltage function,you can freely control the voltage for each sweep section.
It is a signal analysis equipment that can simultaneously measure Frequency Response, SPL, THD, Phase, Polarity, Rub & Buzz, and L / R Balance occurring in Bluetooth Speaker / Earphone. The measurement screen can be scaled or closed as needed to measure.
Measurement conditions are saved in Project units.
A project can consist of multiple signal paths.
At this time, it is possible to configure multiple signal paths so that dozens of measurements are automatically measured.
• L/R Balance : L / R Balance, an important inspection item of stereo earphone, can be measured and its error range can be managed.
External type for driving sound source for measuring call microphone amplifier is included. Simple because no RF shielding box for measurement is required
Configuration is possible.
Since the address of the Bluetooth device can be read directly with a barcode or QR code scanner, pairing is possible without putting the Bluetooth device in the RF shielding box. This can improve the measurement time by using multiple measuring instruments in an open space, such as a production line, so that they do not interfere with each other.
You can use various types of microphones and artificial ears. You can measure USB-C Type earphone products with Codec. The characteristics of the receiver and the characteristics of the microphone for the call can be measured continuously.
In addition, it is possible to test the function of the earphone volume.
