Description
The National Instruments PXI-1422 IMAQ Device is a versatile imaging solution designed to cater to a wide range of applications with its customizable 64 KB-by-16 bit Lookup Table (LUT), which can also be configured as two separate 256 B-by-8 bit LUTs for enhanced imaging tasks such as contrast enhancement, data inversion, gamma manipulation, and other nonlinear transfer functions.
It is available in two model numbers, 777933-01 which is compatible with RS-422 Digital Cameras, and 777933-02 designed for LVDS Digital Cameras, allowing for flexibility in camera selection based on the digital interface.
The device includes a Multiple-Tap Data Formatter that adeptly reorders information from up to two 8-bit taps, accommodating variable scanning directions to ensure proper image assembly regardless of the camera’s data output configuration.
Enhancing system integration, the Trigger Control and Mapping feature meticulously monitors and controls both external and RTSI bus trigger lines, providing a total of eight triggers—four external and four RTSI bus triggers—to synchronize imaging processes with other system components.
Moreover, the High-Speed Timing Circuitry of the NI PXI-1422 IMAQ Device, built with rapid counters, delivers precise and real-time control signals that can be mapped to trigger lines, enabling the generation of exact pulses and pulse trains, essential for timing-critical imaging tasks.
