### 4. Functionality

The PXI-9820D/512 operates as a high-speed digitizer for capturing analog waveforms and converting them into digital data for analysis. Each of its two channels uses a 14-bit pipeline ADC capable of simultaneous sampling. The module supports three timebase sources—internal 60 MHz, external sine wave, and SSI timebase—allowing flexible synchronization with external systems.

In dual-channel mode, both channels sample at up to 65 MS/s. In single-channel “ping-pong” mode, the two ADCs alternate sampling to achieve up to 130 MS/s. The onboard SDRAM stores large data sets before transferring them to the host system via DMA, ensuring uninterrupted acquisition even when PCI bandwidth is limited.

Use Cases and Applications:
- Radar and sonar waveform capture
- Ultrasound imaging and analysis
- Software-defined radio (SDR)
- RF signal analysis and transient capture
- Automated test equipment (ATE)
- Communication system diagnostics
- Scientific and industrial data acquisition

Compatibility:
- PXI and CompactPCI chassis
- Supported operating systems: Windows 7/8 (x86/x64), Linux
- Supported software environments: LabVIEW, MATLAB, C/C++, Visual Basic, Visual Studio.NET
