### 4. Functionality

The PCI-9820D/512 digitizer captures high-speed analog signals and converts them into 14-bit digital data for analysis or storage. It uses two 65 MS/s pipeline ADCs for simultaneous sampling of two channels. In single-channel “ping-pong” mode, both ADCs operate alternately to achieve up to 130 MS/s sampling.

Use Cases and Applications:
- Radar signal acquisition
- Ultrasound imaging and diagnostics
- Software-defined radio (SDR)
- RF and communication system analysis
- Transient signal capture and analysis
