### 4. Functionality

Operation Principle:
The AI‑1204Z‑PCI converts analog voltage signals into 12‑bit digital data using four simultaneous‑sampling A/D converters. Each channel’s range and termination can be configured independently via software. The board stores sampled data in its 32 M‑sample buffer and transfers it to the host PC through PCI bus‑master DMA, minimizing CPU overhead.

Use Cases & Applications:
- High‑speed data acquisition and waveform capture
- Industrial measurement and control systems
- Scientific instrumentation and laboratory automation
- Vibration, acoustic, or transient signal analysis
- Multi‑channel synchronized sampling systems

Compatibility:
- PCI 32‑bit 33 MHz slots (universal 3.3 V/5 V)
- Windows 2000/XP/Vista/7/Server 2003 (via API‑AIO(WDM))
- Programming languages: Visual Basic, C/C++, C#, Delphi, C++ Builder

Triggering & Control:
Sampling can be initiated or halted by software commands, external LVTTL triggers, or internal event controller outputs. Data comparison triggers allow acquisition based on signal thresholds or ranges. Independent start/stop conditions enable flexible control schemes.

Synchronization:
Multiple AI‑1204Z‑PCI boards can be linked via synchronization connectors (CN3/CN4) using the supplied cable. One board acts as master, distributing clock and trigger signals to up to 15 slave boards for fully synchronized multi‑channel operation.
