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.

In order to learn more about EMVA 1288, please visit http://www.emva.org

Interface

The SP-20000-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 GenICamTM 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-20000-USB uses a Micro B connector which complies with USB3.0. 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-20000-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-20000-USB series

It is necessary to use a PC equippped 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-20000-USB may not work

properly depending on the chipset used in the PC.

1. General

The SP-20000-USB cameras are members of JAI’s new “Spark Series.”They provide both high resolution

and a high frame rate with excellent image quality for machine vision applications. The SP-20000M-USB

is a monochrome progressive scan COMS camera and the SP-20000C-USB is the equivalent Bayer mosaic

progressive scan CMOS camera. Both are equipped with CMOS sensors offering a 35 mm full size image

format, a resolution of 20 million pixels, and a 4:3 aspect ratio. They provide 16 frames per second for

continuous scanning with 5120 x 3480 full pixel resolution for both monochrome and raw Bayer output.

8-bit, 10-bit and 12-bit outputs can be selected for both monochrome and raw Bayer formats. The new

cameras feature a USB3 Vision interface. A full pixel readout or partial scan readout mode can be

selected depending on applications.

The SP-20000-USB has various comprehensive functions needed for automated optical inspection

applications, such as solid state device inspection or material surface inspection. They incorporate video

processing functions such as a look-up table, flat field shading compensation and blemish compensation

in addition to fundamental functions such as trigger, exposure setting and video level control.

5. Input and output

5.1 USB 3.0 Interface specifications

The SP-20000-USB employs a USB 3.0 interface for video and data transfer. USB 3.0 is an upgraded

version of USB 2.0 widely used in the industry. Its transfer rate is 5 Gbps, which is 10 times faster than

the 480 Mbps rate of USB 2.0. USB 3.0 employs full-duplex system which executes both transmitting

and receiving at the same time. USB 3.0 has downward compatibility to USB 2.0 but in the SP-20000-USB,

USB 2.0 cannot be used because the performance is not guaranteed.

The connector used for USB 3.0 in the SP-20000-USB is a Micro B Type connector with a USB 3.0 form

factor.

5.3.3 Line Mode

Indicates the status of the item selected in Line Selector. (INPUT or OUTPUT)

5.3.4 Line Inverter

Inverts the signal polarity for the item selected in Line Selector. (False=Positive, True=Negative)

5.3.5 Line Status

Indicates the status of the selected signal (input or output) (True=High, False=Low)

5.3.6 Line Format

Indicates the interface category of input and output for the selected signal.

Category: No connect, TTL, LVDS and OPTO coupled

5.3.6 GPIO

GPIO is a general interface for input and output and controls the I/O for trigger signals and other valid

signals and pulse generators. By using this interface you can control an external light source, make a

delay function for an external trigger signal, or make a precise exposure setting together with a PWC

trigger.
