Video Processor Boards




ARC-42 - Dual Readout Infrared Video Board
    




The dual readout infrared video processing board amplifies, filters and digitizes the video output from two channels of an infrared array and supplies programmable DC bias voltages to it. Two 16-bit analog-to-digital (A/D) converters simultaneously digitize signals from two video outputs at a maximum pixel rate of 1 MHz.

ARC-45 - Dual Readout CCD Video Board
    




The dual readout CCD video processing board serves two functions - processing and digitizing video outputs from two CCD video channels and supplying DC bias voltages to the CCD. Two 16-bit analog-to-digital (A/D) converters simultaneously digitize signals from two video outputs at a maximum pixel rate of 1 MHz. The DC bias supply section of the board provides ten low noise, digitally programmable voltage outputs with a variety of voltage ranges suitable for direct connection to CCDs. There is a three op amp differential input circuit on each of the two video processors, suitable for connection to the outputs of preamps located next to the CCD that drive long cables. There is also a single ended circuit that can be connected directly to the CCD video output pin.

ARC-46 - Eight Channel IR Video Board
    




The eight channel IR video processor contains eight identical video processors, each consisting of a balanced differential input stage, an offset nulling and gain stage, a resettable integrator and an 18-bit, 0.5 microsecond conversion time A/D converter. Image data is transferred to the controller backplane through a FIFO circuit, and DC bias supplies provide seven programmable voltage outputs for powering the detector.

ARC-48 - Eight Channel CCD Video Board
    




The 8-channel CCD video processing board serves two functions - processing and digitizing the video outputs from one to eight CCD video channels and supplying DC bias voltages to the CCD(s). It contains eight identical video processing circuits that can simultaneously process and digitize signals from eight CCD video outputs. Eight 18-bit analog-to-digital (A/D) converters are provided on the board, along with a 16-bit data pathway to the backplane. The DC bias supply section of the board provides 32 separate low noise, digitally programmable voltages with a variety of voltage ranges suitable for direct connection to CCDs, and a video offset voltage for each of the eight video processors.
