9.3.7PWC PIV Mode

The PWC PIV is based on PIV Fixed Exposure. In this mode, the first time exposure is controlled by the pulse width of the external trigger, which is similar to PWC mode. The real exposure time of the first image is equal to the pulse width of the external trigger.

The maximum trigger frequency in this mode is equal to 1/ (transfer time of two frames + exposure time of the first image).

The minimum active period of the external trigger is 10 pixel clocks (250ns)
