### 4. Functionality

The PCI-9820W/128 operates as a high-speed digitizer for capturing analog signals and converting them into digital data for analysis. Two 14-bit pipeline ADCs simultaneously sample input signals 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 independent of PCI bus bandwidth. Data can be transferred to host memory via scatter-gather DMA or streamed directly through the 3k-sample FIFO for real-time applications.

Use Cases and Applications:
- Radar and sonar waveform capture
- Ultrasound imaging and analysis
- RF and communication signal analysis
- Software-defined radio (SDR)
- Transient signal recording and analysis
- Automated Test Equipment (ATE)
- Automotive and aerospace testing
- Laboratory and biomedical instrumentation

Compatibility:
- PCI 32-bit, 33 MHz bus (3.3V/5V universal)
- Compatible with Windows and Linux operating systems
- Supported by ADLINK’s software suite and third-party environments (LabVIEW®, ActiveX, C/C++).
