### 4. Functionality

Analog Input Operation:
The AD12‑64(PCI) performs analog‑to‑digital conversion of voltage signals into 12‑bit digital data. Each channel’s range and mode (single‑ended/differential) are software‑configurable. Sampling can be continuous or event‑triggered, with data stored in FIFO or ring buffer memory structures.

Sampling Control:
- Internal Clock Mode: Uses onboard clock generator for periodic sampling.
- External Clock Mode: Synchronizes sampling to an external TTL‑level clock input.
- Software Control: Allows manual or programmatic sampling initiation.

Triggering:
Sampling can start via software command, external trigger input, or analog level comparison. Stop conditions include sample count completion, external trigger, or software abort.

Digital I/O:
Four TTL‑level inputs and four TTL‑level outputs enable external device control, status monitoring, or synchronization with other systems.

Timer Function:
Programmable timer generates periodic TTL pulses for timing or synchronization tasks. Period adjustable from 500 ns to over 1 s in 250 ns increments.

Use Cases & Applications:
- Industrial process monitoring and control
- Laboratory instrumentation and test automation
- Data logging and signal analysis
- Sensor array acquisition (temperature, pressure, vibration)
- Embedded system development requiring multi‑channel analog input

Compatibility:
- Operating Systems: Windows 7/8/10/11, Windows Server 2003–2019, Linux kernel 2.6+
- Software Environments: Visual C++, Visual Basic, Delphi, C++ Builder, gcc, LabVIEW
- Driver Libraries: API‑AIO(WDM), API‑AIO(98/PC), API‑AIO(LNX)
