10.4.19 SetPeriodHi
Sets trigger period (high 16 bits) when operating in internal trigger mode. This command, along
with SetPeriodLo defines the internal trigger period as a 32 bit value. The actual trigger period
depends on the selected frame rate. The formulas for calculating the period are;
30fps; Period(seconds)= (32 bit trigger value) * 250ns
60fps; Period(seconds)= (32 bit trigger value) * 125ns
Minimum = 33.33ms for 30fps frame rate
Minimum = 16.67ms for 60fps frame rate
