ZE-0948 USB Audio Interface
The ZE 0948 is the ideal USB Audio Interface for DIRAC, and for general sound and vibration measurements. The input level range, frequency response and dynamic range are well suited for professional applications. This is not always the case with the built-in sound card of a desktop or laptop PC.
The analog inputs and outputs are phase-synchronous, allowing the use of de-convolution techniques such as with MLS and swept sine measurements.
USB's Plug & Play architecture and the compatibility with native Microsoft™ Windows™ and Apple Computer™ Mac OS drivers ensure instant use without driver installation.
Applications
The ZE 0948 can be used to measure acoustical systems and signals, and to record and playback audio signals. Some typical applications would be:
- Acoustical measurements
- Vibration measurements
- Electronic system measurements
- MLS or swept sine based measurements
- Professional audio
