Basler sprint Mono Cameras

4.3.2

Example of Calculating the Maximum Allowed 
Line Rate / Minimum Line Period

Assume that you are working with an spL4096-140km. Also assume that the camera is set for the 
dual line [ Max 140 kHz] line acquisition mode and 8 tap 8 bit video data output mode. The AOI 
starting pixel is set to 1249, AOI length is set to 2400, and the exposure time is set to 4 µs. The 
stamp feature and horizontal binning are disabled.

First, you must determine the max segment AOI pixels. With the current settings 800 AOI pixels 
would be included in segment 1 and 1600 AOI pixels would be included in segment 2. In this case, 
the max segment AOI pixels is 1600.

Next, use the four formulas to calculate the maximum allowed line rate:

Formula 1

:

Max Lines / s = 188679

Formula 2

:

Max Lines / s = 175438

Formula 3

:

Max Lines / s = 266666
