6.4.1 Burst Frame Count
The acquisition mode under external trigger includes single frame mode and multiple frame mode.
In different modes, the relation between camera exposure time and readout time varies.
Single Frame Mode
Under this mode, the camera exposes once only when inputting one trigger signal. The camera
exposure time can be set as a larger value to achieve Bulb Shutter. The sequence diagram of single
frame mode is shown below.

Multiple Frame Mode
In this mode, the camera outputs multi-frame images by receiving one trigger signal. You can set
the burst number by clicking Acquisition Control > Acquisition Burst Frame Count, and the range
is from 1 to 1023.
If Acquisition Burst Frame Count = 1, it is single frame mode. If Acquisition Burst Frame Count = 3,
then 1 trigger signal will output 3 frames image. The sequence diagram of burst mode is shown
below.
