Edge
: Select the active triggering edge of the trigger pulse:
•
Rising
–
Uses the rising edge of the trigger pulse to start the exposure.
•
Falling
–
Uses the falling edge of the trigger pulse to start the exposure.
Overlap
: Select how to handle the next trigger pulse if it arrives while the previous
triggering cycle is in process:
•
Ignore. Camera ignores the next trigger and continues its present operation.
•
Accept. Camera uses the next trigger. The camera will stop the present
operation, then reset and start the new trigger cycle.
De-bounce
: This is designed to prevent multiple triggerings from ringing on the trigger
input pulses. The camera ignores additional triggers received during the de-bounce time.
Set the de-bounce time between 0 and 65535 microseconds.
Glitch Filter
: Sets the minimum trigger pulse width. The camera ignores pulses with a
width shorter than the selected value, which range from 0 to 65535 microseconds.
Exposure Delay
: Sets the delay between the trigger pulse active edge and beginning of
the exposure. You can set the delay from 0 to 16777215 microseconds.
Frames per trigger
: When the Mode is Standard, this option lets you select the number of
frames to capture (expose) and read out per trigger. Select from 1 to 65530 or CONT
(continuous) frames.
Trigger Strobe Options
The camera can send a strobe pulse to synchronize the camera to an external light source.
The Trigger Strobe Options section lets you enable a strobe pulse with each trigger. From
the Mode drop-down list, select from the following options:
•
Off
•
Strobe 1
•
Strobe 2
•
Both
You can set a delay with respect to the trigger pulse active edge from 0 to 16,777,215
microseconds (~16.8 seconds).
3.8 AEC/AGC
Automatic exposure control (AEC) and automatic gain control (AGC) enables the camera
to maintain the same image brightness under variable lighting conditions. The automatic
exposure and gain control process drives the exposure and gain to achieve a target
luminance level (in counts) specified in the Limit settings.
AEC/AGC Control also provides real-time statistics on the camer
a’s exposure time, gain,
and luminance values. When the camera’s exposure or gain limit is reached, an indicator
light on the screen changes color from green to red.
