CHR70M Version: v3 Evaluation System Manual Page 6 of 15 RAME GRABBER AND A frame grabber card which can accept the Medium and Full CameraLink interface was chosen to complete the test system interface. The NI PCIe-1433 allows raw image data to be dumped at 4.8Gbit/s on the PC. This card is fitted in a PCI Express slot of the test system PC and uses two dedicated cables to connect to the CHR70M board. -

Page 12: Image Area
CHR70M Version: v3 Evaluation System Manual Page 11 of 15 Every register setting in this list refers to a sensor register (see data sheet for complete register map). The user of the evaluation system can only change the ‘value’ of the registers. The other entries are informational. (Tip: the register addresses (third column from the right) match the address values in the register map in the datasheet). -

SAVE BUTTONS: Clicking these buttons will save the requested image(s) in a specific file format. Set the path and name and the software will automatically add the frame number per image. -
Page 14: Column Offset Calibration
CHR70M Version: v3 Evaluation System Manual Page 13 of 15 4.4 C OLUMN FFSET ALIBRATION Because the offsets of the different channels can be different (and also the offsets of the PCB ADC's) it is recommended to change the offset registers of every channel until an even image is received. Manually adjusting these registers can be difficult, that is why the software provides an automatic calibration for this. - Page 15 CHR70M Version: v3 Evaluation System Manual Page 14 of 15 FIGURE 1: BEFORE CALIBRATION FIGURE 2: AFTER CALIBRATION © 2014 CMOSIS bvba...
