What is it? An audio analyzer measures and quantifies analog and digital audio signal quality with a single box. It’s built with a high quality signal source and a high performance analyzer. It can measure frequency, level/amplitude, distortion, noise, signal-noise-ratio (SNR), sweep, harmonics, SINAD and more. It also provides measurements like an oscilloscope or spectrum analyzer.
Who needs it? Customers who develop any devices/circuits with a speaker, earphone jack, or microphone. For example: two-way radio, walkie-talkie, mobile phone, home-theater, power amplifier, speaker, laptop/PC, audio mixer, audio synthesizer, etc.
Target application: Radio, mobile phone, broadcast device, consumer audio, acoustic, automotive infotainment, analog component test, etc. It is a useful tool for R&D design/verification engineers, technicians and operators in both automatic and manual operations.
Areas of growth: VoLTE and voice quality test. |

Key Product Differentiator: The industry widest audio measurement bandwidth of 1.5 MHz in dual-channel useful to measuremore harmonics and view the out-of-band noise/signal of D-to-A converter, Class-D amplifiers and switching power supplies in a spectrum analyzer-like user interface. |
