### 4. Functionality

Operation Principle:
The DAQ-2006 performs simultaneous analog-to-digital conversions across four differential channels using dedicated ADCs. Each channel’s signal is amplified, digitized, and buffered in onboard FIFO memory before being transferred to system memory via DMA. Analog outputs are generated through dual 12-bit DACs capable of waveform generation, synchronized with analog input operations.

Use Cases and Applications:
- Automotive and aerospace testing
- Transient signal capture and analysis
- Automated test equipment (ATE)
- Process control and industrial automation
- Biomedical and biotech instrumentation
- Laboratory data logging and waveform generation

Compatibility:
- PCI bus (32-bit, 3.3 V or 5 V signaling)
- Compatible with ADLINK terminal boards (DIN-68S/1M) and SSI synchronization cables (ACL-SSI-2/3/4)
- Software integration with LabVIEW®, MATLAB®, Visual Studio, and Linux C/C++ environments
