If you are using a software trigger to start each frame acquisition, the frame rate will be determined
by how often you apply a software trigger to the camera, and you must not attempt to trigger frame
acquisition at a rate that exceeds the maximum allowed for the current camera settings.

6.4.2.2
If the camera is currently in the process of acquiring a frame, it may not be ready to receive a new
software frame start trigger and begin acquiring a new frame.
You can use the acquisition status feature to determine whether the camera is ready to perform a
new frame acquisition. If you check the acquisition status before you issue each software frame
start trigger, you can avoid triggering the camera at a rate that exceeds the maximum allowed with
the current camera settings.
To determine the acquisition status of the camera:
Use the Acquisition Status Selector to select the Frame Trigger Wait status.
Read the value of the Acquisition Status parameter.
If the value is set to "false", the camera is not ready to receive a software frame start trigger, if
the value is set to "true", the camera is ready to receive a software frame start trigger.
