### 4. Functionality

The DAQe‑2214 performs simultaneous analog signal acquisition and generation with precise timing control. Analog inputs are multiplexed, amplified, and digitized by a 16‑bit ADC. The card supports both single‑ended and differential configurations, selectable per channel, allowing mixed‑mode operation. The onboard FIFO buffers ensure continuous data streaming without loss.

Analog outputs are generated by two 12‑bit DACs capable of waveform generation at up to 1 MS/s. The card supports software‑triggered or hardware‑triggered waveform generation, including iterative and re‑triggered modes.

Digital I/O lines can be configured as inputs or outputs for control and monitoring tasks. Two 16‑bit counters provide event counting, frequency measurement, and pulse generation.

Typical Applications:
- Automated Test Equipment (ATE)
- Laboratory and process automation
- Transient signal measurement
- Automotive and cable testing
- Biotech instrumentation
- Data logging and control systems

Compatibility:
- Operating Systems: Windows 7/8 x86/x64, Linux
- Software Environments: LabVIEW®, MATLAB®, C/C++, Visual Basic, Visual Studio .NET
