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 x 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
on page 245). The default value here is set to 20 µs.
Exposure time of Guppy PRO F-503 (CMOS)
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 reg-
ister: EXTENDED_SHUTTER
