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:
Note

The minimum shutter time (without offset) is 179 µs.
