Key Features
- 8 simultaneous analog input and output channels
- Multichannel crosstalk and phase measurement across all channels
- Typical THD+N less than -107 dB across all channels
- HDMI and Dolby/DTS compliance testing
- Support for Dolby TrueHD, dts-HD, and other encoded formats
- Frequency range 5 Hz to 80.1 kHz with 3 ppm accuracy
- Maximum balanced amplitude 14.4 Vrms with ±0.05 dB accuracy
- Intuitive UI with one-click measurements and rich graphing
- API support for VB.NET, C#.NET, and LabVIEW automation
- MS Word report generation for results and graphs
Applications
- Testing of home theater receivers and consumer audio devices
- Professional audio mixing console development and validation
- HDMI and digital audio interface compliance verification
- Multichannel audio device quality assurance
