set fps doesn't match camera strobe out frequency

[XieLuanLab]

Hi,

I'm using an Imaging Source DMK 37BUX287 camera for recording and have set the frame rate to 100 fps, as shown in the image below:

Although the saved video file indicates a frame rate of 100 Hz, when I connect the camera's strobe output to an oscilloscope, I only measure a frequency of 60 Hz:

I've also tried adjusting the frame rate in IC Capture software, where the fps and the strobe output frequency align. So I guess there might be some issues in dlclive camera control I/O.

Thank you for your help.
