Acquisition Control AW00118303000
120 Basler racer GigE
Example
Assume that you are using an raL2048-48gm camera at full resolution (2048 pixels), assume that
you want to use the minimum allowed line acquisition period and the default value for C
1
.
Also assume that the other relevant settings are in accord with operation at the minimum allowed
line acquisition period.
At full resolution, the camera is capable of a minimum line acquisition period of 19.7 µs
(corresponding to a maximum allowed line acquisition rate of approximately 51 kHz; see
Section 1.2 on page 2).
Accordingly, the corresponding minimum allowed ExLSTrig signal period where overtriggering is
avoided is 19.7 µs.
From condition number four follows the maximum possible exposure time that is compatible with
(default) maximum overlap:
E = min. ExLSTrig Signal Period - C
1
= 19.7 µs - 5.4 µs = 14.3 µs
Therefore, when operating the camera at a line acquisition period of 19.7 µs (involving maximum
overlap) and using the default value for C
1
,
the maximum possible exposure time is 14.3 µs. When
also considering the above condition number one, it follows that the exposure time can range
between 2 µs and 14.3 µs to remain in accord with camera operation at a line acquisition period of
19.7 µs (and a line rate of approximately 51 kHz).
If you increase an exposure time beyond its upper limits the related extent of
overlap and the acquisition line rate will decrease. When extending exposure time
even further, consecutive line acquisitions will eventually not overlap at all.
