AW00118508000 Acquisition Control
Basler racer Camera Link 90
Formula 3 calculates the maximum line rate based on the amount of time it takes to transmit the
pixel data for an acquired line from the camera to the host computer:
Where: CL Clk is the Camera Link pixel clock speed for your camera model (see Section 8.1
on page 100
Taps is the number of Camera Link taps being used as determined by the current Cam-
era Link tap geometry setting (see Section 7.2 on page 98)
AOI Width is the width of the AOI based on the current AOI width setting (see
Section 8.4 on page 107)
Once you have determined the maximum allowed line rate, you can easily determine the minimum
allowed line period:
Example
Assume that you are using an raL2048-80km camera set for an exposure time of 190 µs. Also
assume that you are using full resolution (2048 pixels), the default value for C
1,
a Camera Link clock
speed of 32.5 MHz, and the 1X4 Camera Link tap geometry that provides 4 taps.
Factor 1 (sensor readout, nominal value):
Max Lines/s = 80000
Factor 2 (exposure time):
Max Lines/s = 5117
Formula 3 (data transmission):
Max Lines/s = 62620
