CRY6151B Electroacoustic Analyzer Introduction CRY6151B electroacoustic analyzer is the newest electro-acoustic analyzer developed by CRY Sound with powerful functions and strong stability. It can measure the performance of 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, 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. Contains soundcard, power amplifier, signal conditioning module and USB communication module. All of above superior modules contribute to various types of electro-acoustic device testing combined with software. 2. Compact design, simple USB data communication, which meet customer requirements for various types of test environment; Software： 1. Compatible with Windows XP 32bit and Windows 7 32bit 2. Support a variety of stimulus type, including RMS, Rapid stepped sweep, Precise stepped sine sweep, Multitone, White noise and Pink noise. 3. Single sweep measure frequency response, sensitivity(SPL), distortion(THD), impedance, F0, phase, balance, polarity, etc. 4. Can test the Bluetooth audio equipment with automatic matching (no manual click); 5. Powerful sequence editing and preservation function, equipped with signal generator and multimeter. To better adapt to customers in the laboratory and production line applicat
