Introduction
EMVA 1288
With regard to signal to noise ratio in this manual, specifications measured by EMVA 1288 are used
together with specifications by a traditional measurement method.
EMVA 1288 is a more complete measurement that considers multiple noise sources, including random
noise, pattern noise, and shading. Additionally, EMVA 1288 incorporates temporal variances in pixel
output 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 RMS
variances over time, EMVA 1288 SNR measurements are inherently lower than the traditional SNR
measurements given by manufacturers. However, the comprehensive nature combined with rigid
test parameters, means that all manufacturers’ are measuring their products equally and EMVA 1288
tested parameters can be compared among different manufacturers’ products.

Interface
The SP-5000M-CXP4 and SP-5000C-CXP4 employ CoaXPress as an interface system. In order to
connect the camera to a PC, it requires the use of a Frame Graber board and the appropriate coaxial
cable(s). The maximum video transfer rate per coaxial cable is 6.25 Gbps. In addition to video
information, power and control signals can be transferred to the camera over this interface. For
detailed specifications, please refer to “JIIA-NTF-001-2010” published by Japan Industrial Imaging
Association, http://www.jiia.org.
Computer used for SP-5000 series
In order to get proper performance from this camera, it is necessary to use a PC equipped with a
PCIe 2.0 slot with a size and capacity of 16 lanes or higher (x16 or x32).
Frame grabber boards used with SP-5000 series
As 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 interface
connectors and it is recommended that a frame grabber board with at least four interface
connectors be used in order to maximize camera performance.
Cables used with SP-5000 series
For 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 used
to connect the camera must have a 75Ω 1.0/2.3 DIN-type plug at the camera side. An ordinary BNC
cable cannot be used.
