### 4. Functionality

The PCI-9820D/128 digitizer converts analog signals into high-resolution digital data for analysis and processing. It employs two 14-bit pipeline ADCs operating at up to 65 MS/s per channel. In single-channel “ping-pong” mode, both ADCs interleave to achieve up to 130 MS/s sampling.

Captured data is stored in onboard SDRAM, allowing long-duration waveform recording without PCI bus limitations. The scatter-gather DMA engine transfers data efficiently to host memory, while the 3k-sample FIFO enables real-time streaming for lower data rates.

Use Cases and Applications:
- Radar and sonar waveform capture
- Ultrasound and medical imaging
- Software-defined radio (SDR)
- RF and communication signal analysis
- Transient event recording
- Automated test equipment (ATE)
- Automotive and industrial signal monitoring
- Scientific and laboratory research

Compatibility:
- PCI 32-bit, 3.3 V/5 V universal slot
- Supported OS: Windows 98/NT/2000, Linux
- Supported software: LabVIEW®, ActiveX, DAQBench
