Camera Control
Parameter Description
Internal Line Camera line rate in a range from 300 Hz up to 80 kHz (2k, 4k, 8k) or 48 kHz
Rate (16k).
This feature is only available when the camera is in Internal Mode (free
running): that is, the line trigger is disabled
Exposure Time Set the operation mode for the camera's exposure. Trigger Width is only
Source available when Trigger Mode is enabled.
Exposure Time Sets the exposure time (in microseconds). Exposure Time Source feature
must be set to Timed.

Internal Programmable Exposure
The Linea CL in the Internal Programmable Exposure mode is the default free- running mode with
the external trigger off and internal exposure control. This mode is not synchronized to an external
signal. Line rate is the dominant factor when adjusting the line rate or exposure time. When setting
the line rate exposure time will decrease (if necessary) to accommodate the new line rate. When
adjusting the exposure time the range is limited by the line rate and has the following features:
 The Trigger Source feature (see I/O Control category) selects an internal signal as trigger.
 Programmable internal trigger, where the maximum line rate limit is related to the Exposure
Time feature.
 Exposure duration is user programmable (exposure maximum is dependent on the line rate).
Minimum exposure (in µs) is model dependent.

LVAL
1. Exposure time > 4s (all models)
2. Sensor readout time = 12.5s (2k, 4k, 8k) or 20.8s (16k)
3. LVAL delay = ~14.5s (2k, 4k), 26s (8k) or 41s (16k)
36  Camera Operation
Trigger Uses the width of the current line trigger signal pulse to
Width control the exposure duration.
Timed The exposure duration time is set using the Exposure Time
feature and the exposure starts with the Line Start event.
