### 4. Functionality

The PCI-9812A functions as a high-speed digitizer for analog signals, converting continuous analog waveforms into digital data streams for processing and analysis. Each of the four channels uses a dedicated 12-bit A/D converter, enabling simultaneous sampling without inter-channel delay. The card’s internal 40 MHz clock or external clock sources control the sampling rate, while the onboard FIFO buffer temporarily stores data before DMA transfer to host memory.

- Vibration and acoustic analysis
- Ultrasonic and medical imaging
- High-speed signal digitization (IF/baseband)
