Minimum shutter time of Guppy F-036
Example Guppy F-036
Set Shutter register: 100
100 x 20 μs = 2000 μs
2000 μs/29.89 μs = 66.91
Effective shutter:
66 x 29.89 μs = 1972.74 μs (without offset)
Example Guppy F-503
Set Shutter register: 100
100 x 20 μs = 2000 μs
2000 μs/41.8 μs = 47.85
Effective shutter:
47 x 41.8 μs = 1964.6 μs (without offset)
Exposure time offset
A camera-specific offset is also added to this value. It is different for the camera
models:
