69. y row The LFSR test pattern was chosen because it leads to a very high data toggling rate which stresses the interface electronic and the cable connection In the histogram you can see that the number of pixels of all grey values are the same Please refer to application note ANO26 for the calculation and the values of the LFSR test image 28 Figure 4 15 Ramp test images 8 bit output left 10 bit output right Figure 4 16 LFSR linear feedback shift register test image 4 3 3 Troubleshooting using the LFSR To control the quality of your complete imaging system enable the LFSR mode and check the histogram at full resolution If your frame grabber application does not provide a real time histogram store the image and use a graphic software tool to display the histogram In the LFSR linear feedback shift register mode the camera generates a constant pseudo random test pattern containing all grey levels If the data transmission is error free the histogram of the received LFSR test pattern will be flat Fig 4 17 On the other hand a non flat histogram Fig indicates problems that may be caused either by the cable by the connectors or by the frame grabber A possible origin of failure message can be caused by the CameraLink cable amp which exceeds the maximum length Also CameraLink cables may suffer either from stress due to wrong installation or from severe electromagnetic interfer ence 4 3 Test Images 29
