until you execute an Acquisition Stop command. Once an Acquisition Stop command has been
executed, the camera will not be able to acquire frames until a new Acquisition Start command is
executed.
Acquisition Start Trigger
The acquisition start trigger is essentially an enabler for the frame start trigger.
The acquisition start trigger has two modes of operation: off and on.
If the Trigger Mode parameter for the acquisition start trigger is set to off, the camera will generate
all required acquisition start trigger signals internally, and you do not need to apply acquisition start
trigger signals to the camera.
If the Trigger Mode parameter for the acquisition start trigger is set to on, the initial acquisition status
of the camera will be "waiting for acquisition start trigger" (see Figure 45 on page 81). When the
camera is in this acquisition status, it cannot react to frame start trigger signals. When an acquisition
start trigger signal is applied to the camera, the camera will exit the "waiting for acquisition start
trigger" acquisition status and enter a "waiting for frame start trigger" acquisition status. The camera
can then react to frame start trigger signals. The camera will continue to react to frame start trigger
signals until the number of frame start trigger signals it has received is equal to an integer parameter
setting called the Acquisition Frame Count. At that point, the camera will return to the "waiting for
acquisition start trigger" acquisition status and will remain in that status until a new acquisition start
trigger signal is applied.
As an example, assume that the Trigger Mode parameter is set to on, the Acquisition Frame Count
parameter is set to three, and the camera is in a "waiting for acquisition start trigger" acquisition
status. When an acquisition start trigger signal is applied to the camera, it will exit the "waiting for
acquisition start trigger" acquisition status and enter the "waiting for frame start trigger" acquisition
status. Once the camera has received three frame start trigger signals, it will return to the "waiting
for acquisition start trigger" acquisition status. At that point, you must apply a new acquisition start
trigger signal to the camera to make it exit "waiting for acquisition start trigger".
Frame Start Trigger
Assuming that an acquisition start trigger signal has just been applied to the camera, the camera
will exit from the "waiting for acquisition start trigger" acquisition status and enter a "waiting for
frame start trigger" acquisition status. Applying a frame start trigger signal to the camera at this point
will exit the camera from the "waiting for frame start trigger" acquisition status and will begin the
process of exposing and reading out a frame (see Figure 45 on page 81). As soon as the camera
is ready to accept another frame start trigger signal, it will return to the "waiting for frame start
trigger" acquisition status. A new frame start trigger signal can then be applied to the camera to
begin another frame exposure.
The frame start trigger has two modes: off and on.
If the Trigger Mode parameter for the frame start trigger is set to off, the camera will generate all
required frame start trigger signals internally, and you do not need to apply frame start trigger
signals to the camera. The rate at which the camera will generate the signals and acquire frames
will be determined by the way that you set several frame rate related parameters.
If the Trigger Mode parameter for the frame start trigger is set to on, you must trigger frame start by
applying frame start trigger signals to the camera. Each time a trigger signal is applied, the camera
will begin a frame exposure. When frame start is being triggered in this manner, it is important that
