Auto Mode (srm 0)
In this mode the line rate from the camera will automatically cause a switch between
the gate dark current clear mode and non gate dark current clear mode.
The frequency of when this mode switchover occurs depends on the camera model.
In cases where the line rate is rapidly increased from below the Dark Current Clear
to Immediate Readout Transition Frequency to above the Immediate Readout to
Dark Current Clear Transition Frequency, the first line following this transition will
likely be corrupted.
The table below outlines the artifacts that may be seen during this transition period.
All subsequent lines after this occurrence will be as expected.
In the case of a slow transition (that is, when the EXSYNC line rate increases by less
than 10% of the previous line rate) a line readout will not become corrupt.
There are also limitations on the exposure time when operating in auto mode: If the
line rate exceeds half the maximum line rate, then the exposure time cannot exceed
the time stated in
322H
Table 18
.
Note: DALSA recommends Auto mode for most users.
For information on artifacts that may be experienced while using this mode, see the
Artifacts section below.
