The NI IMAQ PXI-1407 is a monochrome image acquisition module for PXI, PCI, and CompactPCI chassis. It captures video from RS-170 and CCIR sources using an 8-bit flash ADC with progressive scan acquisition. The module supports frame rates of 25, 30, 50, and 60 fps and delivers 256 gray levels with typical signal-to-noise ratio of 48 dB.
