OperationTM/TMC/RM/RMC-2030GE- 61 -10.5.6 PWC PIV ModeThe PWC PIV is based on PIV Fixed Exposure. In this mode, the first time exposure is controlled by thepulse width of the external trigger, which is similar to PWC mode. The real exposure time of the firstimage 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 + exposuretime of the first image).The minimum active period of the external trigger is 10 pixel clocks (250ns)Figure 60.
