SP-5000M-CXP4 / SP-5000C-CXP4- 6 -IntroductionEMVA 1288With regard to signal to noise ratio in this manual, specifications measured by EMVA 1288 are usedtogether with specifications by a traditional measurement method.EMVA 1288 is a more complete measurement that considers multiple noise sources, including randomnoise, pattern noise, and shading. Additionally, EMVA 1288 incorporates temporal variances in pixeloutput by capturing 100 frames of data and computing the RMS variations over the captured frames.Because of the comprehensive nature of the noise analysis and the additional consideration for RMSvariances over time, EMVA 1288 SNR measurements are inherently lower than the traditional SNRmeasurements given by manufacturers. However, the comprehensive nature combined with rigidtest parameters, means that all manufacturers’ are measuring their products equally and EMVA 1288tested parameters can be compared among different manufacturers’ products.In order to learn more about EMVA 1288, please visit http://www.emva.orgInterfaceThe SP-5000M-CXP4 and SP-5000C-CXP4 employ CoaXPress as an interface system. In order toconnect the camera to a PC, it requires the use of a Frame Graber board and the appropriate coaxialcable(s). The maximum video transfer rate per coaxial cable is 6.25 Gbps. In addition to videoinformation, power and control signals can be transferred to the camera over this interface. Fordetailed specifications, please refer to “JIIA-NTF-001-2010” published by Japan Industrial ImagingAssociation, http://www.jiia.org.Computer used for SP-5000 seriesIn order to get proper performance from this camera, it is necessary to use a PC equipped with aPCIe 2.0 slot with a size and capacity of 16 lanes or higher (x16 or x32).Frame grabber boards used with SP-5000 seriesAs the SP-5000M-CXP4 and SP-5000C-CXP4 employ CoaXPress as an interface system, a CoaXPress-compliant frame grabber board is required. Both cameras have four CoaXPress interfaceconnectors and it is recommended that a frame grabber board with at least four interfaceconnectors be used in order to maximize camera performance.Cables used with SP-5000 seriesFor the CoaXPress interface, coaxial cables are used. In the SP-5000M-CXP4 and SP-5000C-CXP4,they use 75Ω 1.0/2.3 DIN receptacles (Amphenol ACX1785-ND or equivalent). The coaxial cable usedto connect the camera must have a 75Ω 1.0/2.3 DIN-type plug at the camera side. An ordinary BNCcable cannot be used.
