IC testing with multi-channel, multi-format Digital Serial I/O

Spectral Measurement delivers I2S audio testing solutions engineered with first-hand audio equipment design experience.

The dScope can interface directly with digital audio signals at board-level by converting serial audio data such as I2S to AES3 (AES/EBU). It supports also TDM for up to 16 channels of audio data.

Typical applications are in the development and testing of:

  • Board level components such as A-D and D-A converters
  • Modular equipment where audio is passed between modules on serial interfaces
  • Automotive multi-channel audio and
  • Service and fault-finding on digital systems.

With the dScope M1, you can use either the integrated VSIO or the dSNet VSIO adapter.
