If bit 9 is set to 1 all of the other bits will automatically be set to 1 This means that you should only use the shift once setting when your pixel readings with no digital Shift Twice When the camera is set to shift twice the output from the camera will include bit 7 through bit 0 from the ADC The result of shifting twice is that the output of the camera is effectively multiplied by four For example assume that the camera is set for no shift that it is viewing a uniform white target and that under these conditions the reading for the brightest pixel is 20 If we changed the digital shift setting to shift twice the reading would increase to 80 ADC bit bit bit bit bit bit bit bit bit bit 9 8 7 6 5 4 3 2 1 0 Shifted Twice Aone D ital shift are all below 64 If bit 9 or bit8 is setto 1 all of the other bits will automatically be setto 1 This means that you should only use the shift twice setting when your pixel readings with no dig BASLER A400k Basic Operation and Features 3 7 3 Precautions When Using Digital Shift There are several checks and precautions that you must follow before using the digital shift feature The checks and precautions differ depending on whether you will be using the camera in 10 bit output mode or in 8 bit output mode If you will be using the camera in 10 bit output mode make this check 1 Use binary commands or the Camera Configuration Tool

Frame Period Gain and Offset parameters The common characteristic among these parameters is that they are expressed as rational numbers These numbers are on a continuous scale rather than on a scale of discrete integers Any one of the parameters expressed as rational numbers can be set on a raw scale or on an absolute scale A raw scale is simply a range of integer values that has no defined units An absolute scale is a range of floating point values that has defined units Let s look at the Exposure Time parameter as an example Setting the Raw Exposure Time If you adjust the exposure time by writing a value to the Raw Exposure Time field of the Exposure Time CSR you can write any integer value from 1 to 4 192 982 decimal Writing an integer value to the exposure time register sets the exposure time but it doesn t directly tell you how many microseconds of exposure time you will be getting from the camera at that setting To determine the microseconds of exposure time you are getting at a particular raw exposure time setting you must use the formula microseconds raw setting x 4 56 us For example if the Raw Exposure Time field is set to 3 decimal microseconds raw setting x 4 56 us microseconds 3 x 4 56 us microseconds 13 68 So with the Raw Exposure Time field set to 3 the camera would be set for 13 68 us of exposure BASLER A400k 4 13 Configuring the Camera Setting the Absolute Exposure Time If you adjust the
