NI IMAQ PCI-1408 Image Acquisition Module

The NI IMAQ PCI-1408 is a monochrome image acquisition module for PCI bus systems that captures and digitizes analog video signals for computer-based processing and analysis. The board accepts standard video formats—PAL, RS-170, NTSC, and CCIR—plus numerous nonstandard imaging devices across four video input sources. An 8-bit flash ADC digitizes incoming signals at pixel clock rates between 5–20 MHz, while an 8-bit look-up table enables real-time image adjustments. Maximum spatial resolution reaches 1 Mpixels (2048 × 1024 pixels). Two operating modes—VIDEO0 and External CLK—support both differential and referenced single-ended input configurations via BNC or 25-pin DSUB connectors. Programmable gain, offset, and acquisition window control allow flexible signal conditioning without manual calibration.
