2)  For 

more 

details 

about 

BinningHorizontal, 

BinningVertical, 

DecimationHorizontal 

and 

DecimationVertical, please refer to 

section 8.3.11

 and 

section 8.3.12

. These four parameters affect 

the transmission time of the image data. 

3)  The ExposureTime is the exposure time when the camera acquires one frame of image. 

4)  The PixelFormat is the pixel format corresponding to the camera output image, including 8 bits, 10 

bits or 12 bits. 

5)  The DeviceLinkThroughputLimit represents the maximum bandwidth of the image transmitted by the 

camera. 

6)  The  MaxUSBControllerThroughputLimit  represents  the  recommended  maximum  transmission 

bandwidth of the camera. If this value is exceeded, frame losing may occur. 

7)  The  AcquisitionFrameRate  represents  the  maximum  value  of  the  frame  rate  control  when  the 

AcquisitionFrameRateMode is set to on, and whether the maximum value can be reached depends 
on whether the camera is affected by other acquisition parameters. 

8)  AcquisitionFrameRateMode indicates  whether  frame rate  control is enabled,  On means frame rate 

control is enabled, and Off means frame rate control is disabled. When frame rate control is enabled, 
the camera acquires images at a frame rate no higher than the AcquisitionFrameRate. When frame 
rate  control  is  disabled,  the  camera  acquires  images  without  being  affected  by  the 
AcquisitionFrameRate.   

When  using  the  frame  rate  calculation  tool,  please  fill  in  the  above  information  of  the  camera  into  the 
corresponding  table.  When  the  filled  value  exceeds  the  range  or  does  not  conform  to  the  rules,  the 
calculation  tool  will  report  an  error.  Please  modify  and  fill  in  the  value  again  according  to  the  prompt 
information. When all parameters are correctly filled in, the FPS shown in the last column of the table is 
the theoretical frame rate currently acquired by the camera, and usually the error between this value and 
the actual frame rate acquired by the camera is no more than 1%.
