Exposure time (shutter) and offset
The exposure (shutter) time for continuous mode and Trigger_Mode_0 is
based on the following formula:
Shutter register value × time base + offset
The register value is the value set in the corresponding IIDC 1.31 register
(SHUTTER [81Ch]). This number is in the range between 1 and 4095.
The shutter register value is multiplied by the time base register value (see
). The default value here is set to 20 µs.
Exposure time of Guppy PRO F-503
The exposure time of Guppy PRO F-503 can be set in row time increments.
The formula for the row time is:
The minimum row time and the row time by maximum resolution are:
The shutter time of Guppy PRO F-503 can be extended via the advanced
register: EXTENDED_SHUTTER

Exposure time offset
A camera-specific offset is also added to this value. It is different for the camera
models:
