Note: Please have a look at the Hardware Real-Time Controller (HRTC) chapter for basic information.

If you need a double acquisition, i.e. take two images in a very short time interval, you can achieve this by using the HRTC.

With the following HRTC code, you will

take an image using TriggerSet and after TriggerReset you have to
set the camera to ExposeSet immediately.
Now, you have to wait until the first image was read-out and then
set the second TriggerSet.

The ExposureTime was set to 200 us.
