National Instruments PXI-1408 IMAQ Device

The National Instruments PXI-1408 IMAQ Device has two distinctive input sources by means of a BNC connector or a 25-stick DSUB port and two diverse information modes—referenced single-ended (RSE) and differential (DIFF) input. When the user utilizes the BNC input for VIDEO0, set the input mode to RSE (W1 populated). When using the 25-pin DSUB port for VIDEO0, set the input mode for either RSE or DIFF.

While in RSE mode, this model’s video input utilizes one analog input line, which interfaces with the video multiplexer hardware. The negative input to the video multiplexer is tied inside to analog ground. When the NI PXI-1408 is in DIFF mode, the video input utilizes two analog input signals. One signal associates with the positive input of the video multiplexer hardware while the other input signal interfaces with the negative input of the video multiplexer hardware.

The PXI-1408 device has an 8-bit flash ADC that changes over the video signals to digital formats, four video signal multiplexers, and programmable gain and displacement. It additionally utilizes a PXI interface for rapid input exchange, DMA dispersion controls that control information exchange between the input and output memory (FIFO) buffers and the PCI bus, non-volatile and Static RAM to set up registers during power-up and program the DMA controllers, and acquisition and control circuits for regions of interest that supervise the video signals. The plate likewise incorporates an effective trigger that incorporates four outer triggers and RTSI bus triggers. Other highlights incorporate inside created or remotely CSYNC, HSYNC, VSYNC, and PCLK synchronization and clock signals.
