Operating hints:
• Increasing Video Gain also increases video noise. Use Video Gain sparingly, or not at all. Leave
it set to 1 whenever possible.
• The Black Level will be adjusted automatically each time you perform an Ultracal! calibration
cycle. Therefore, it is best that you make no changes to this setting. If you alter the Black Level
after an Ultracal!, the calibration will no longer be valid.
3.2.4.3.1 The Four Camera Option
Some enhancements have been made to the four-camera option with the release of software
version 4.00. These enhancements make it possible to automatically sequence data
collection between multiple cameras (up to four). This sequencing only applies to analog
cameras, and the following operating conditions must be met:
• All cameras must be the same type or model.
• The cameras must be Gen-Locked together.
• If cameras with remotely controlled shutters are used the shutter control circuits
must be paralleled to each camera.
The status of the input video is shown in the video enunciator located at the bottom of the
LBA-PC’s main display window. The number shown in this enunciator indicates which camera
is currently selected. If it shows GREEN then camera sync is present. If it shows RED then
there is either no camera connected, or the connected camera is not operating.
3.2.4.3.2 How to Specify Video Gain, Black Level, Shutter, and Video Trigger Level
On the right side of the Camera panel you will see a panel containing a Camera# drop-
down, Video Gain, Black Level, and Shutter controls. Click on the drop-down to select
which camera is affected, the current settings are displayed, and then make the desired
changes. Note that Video Trigger Level, Trigger section below, can also be set for each
camera.
On the toolbar, changing the Video Gain, Black Level, Shutter, and Video Trigger Level
affects only the current camera listed in the video enunciator located at the bottom of the
main display window.
