Before using this camera
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-5000-USB employs a USB 3.0 interface and is in the process of being certified for
compliance with the USB3 Vision standard. USB3
Vision is a new standard interface for machine
vision applications being developed and managed by the AIA (Automated Imaging Association).
USB3 Vision uses USB 3.0 ports that will soon be standard on most PCs (with Windows 7 service
pack and Windows 8 native support expected soon). Components from different manufacturers
will easily communicate with each other.
USB3
Vision also supports the GenICam
TM
standard which is managed by the EMVA (European
Machine Vision Association). The purpose of the GenICam standard is to provide a common
program interface for various machine vision cameras. By using GenICam, cameras from different
manufacturers can seamlessly connect in one platform.
The maximum transfer speed of USB 3.0 is specified at 5.0 Gbps, however effective bandwidth is
reduced by a number of factors including pixel format conversions and the physical interface
components used. The USB3 Vision standard specifies a bandwidth of 2.8 Gbps or greater.
Maximum cable length for passive cables is five meters, but this can be made longer using active
cables.
As for the USB connector, SP-5000-USB uses a Micro B connector which complies with USB 3.0. This
connector has an additional 5-pin plug “stacked” on the side of a standard USB 2.0 Micro B
connector. However, USB 2.0 cannot be used with the SP-5000-USB.
Power supply
Although the USB 3.0 interface is capable of supporting both data and power, the power supplied
through the interface is not sufficient to operate the camera. A separate power supply unit must
be connected to the 12-pin connector.
.
Computer used for SP-5000-USB series
It is necessary to use a PC equipped with a USB 3.0 interface. It is also recommended to use a PC
equipped with slots of better than PC Express 2.0 x 8. Please note that the SP-5000-USB may not
work properly depending on the chipset used in the PC.
