### 4. Functionality

Operation Principle:
The PXI-2022 performs simultaneous analog-to-digital conversion across all 16 channels using dedicated ADCs. Each channel’s signal passes through a programmable gain amplifier and anti-aliasing filter before digitization. The card supports both internal and external timebase sources, enabling precise control of sampling rates and synchronization across multiple modules.

Triggering and Timing:
- Trigger Sources: Software, external digital (SMB TRG I/O), PXI Star Trigger, PXI Trigger Bus (line 5).
- Trigger Modes: Pre-trigger, post-trigger, middle-trigger, and delay-trigger.
- Minimum Trigger Pulse Width: 12.5 ns.
- Timebase Sources: Internal 80 MHz oscillator or external clock (1–20 MHz TTL).
- Sampling Rate Control: Adjustable via 32-bit scan interval counter (Sampling Rate = TIMEBASE / ScanIntrv).

Use Cases:
- Automotive and cable testing
- Transient signal measurement
- Automated Test Equipment (ATE)
- Laboratory and industrial automation
- Biotech and medical instrumentation

Compatibility:
- PXI backplane synchronization via PXI Trigger Bus and PXI Star Trigger.
- Software integration with ADLINK DAQPilot, LabVIEW™, MATLAB®, and DAQBench.
