  • Technical specification

CRY6151B electroacoustic analyzer is the newest electro-acoustic analyzer with powerful functions and strong stability. It can measure the performance of a headset(USB, Bluetooth, ANC), microphone(electret, dynamic, and MEMS), receiver, micro speaker, loudspeaker, communication helmet, etc. The measurement parameters include frequency response, sensitivity, impedance, distortion, resonant frequency(F0), balance, the position of headphones, phase polarity, current and voltage of microphone, signal-to-noise ratio(SNR), directivity, T&S parameters, loudness rating, and so on.

 

   Hardware

1、CRY6151B has high-performance hardware scalable for synchronous 8-channel acquisition/4-channel output.

2、Its hardware includes a sound card module, power amplifier module, signal processing module, USB communication module. It is combined with software to perform various electroacoustic device tests.

3、Its compact chassis design and simple USB data communication method can meet customers’ various test environment requirements.

Software

1、CRY6151 V8.X supports WinXP, Windows 7, and Windows 10 (32 & 64-bit) systems (corresponding drivers to be installed. It is necessary to inform the specific operating environment). It has a user-friendly interface and powerful operation functions.

2、It supports a variety of sweep methods, including effective value, fast-stepping sweep, high precision stepping sweep, multi-tone test, white noise, pink noise, etc. Choose different methods according to different test occasions and test needs.

3、The frequency response, sensitivity (SPL), distortion, impedance, F0, phase, balance, polarity, and other parameters can be measured and determined in one sweep, with the higher test accuracy and faster speed.

4、It is the earliest domestic instrument that can test Bluetooth audio. It is automatically paired without a manual click.

5、It has a powerful sequence editing function, virtual signal generator, multimeter, and complete storage function so that it is fully suitable for customers’ applications in laboratories and production lines.
