Diagnostic Tools
Camera Data File
The Camera Data file includes the operational configuration and status of the camera. This text file
can be downloaded from the camera and forwarded to Teledyne DALSA Technical Customer
support team to aid in diagnosis of any reported issues. See Saving & Restoring Camera Setup
Configurations of the user manual for details on downloading the Camera Data file.
Voltage & Temperature Measurement
The camera has the ability to measure the input supply voltage at the power connector and to
measure the internal temperature. Both of these features can be accessed using the Camera
CamExpertGUI > Camera Information tab. Press the associated refresh button to receive a real-
time measurement.
Test Patterns
–
What can they indicate
The camera can generate fixed test patterns that may be used to determine the integrity of the
CLHS communications beyond the Lock status. The test patterns give the user the ability to detect
bit errors using an appropriate host application. This error detection would be difficult, if not
impossible, using normal image data.
Note: gray images are displayed so that any bit-error will immediately be apparent as colored
pixels in the image
There are five test patterns that can be selected via the Cameras CamExpertGUI > Image Format
tab. They have the following format when using 8-bit data.
•
Each Tap Fixed
o
Starting at 64 increases in by 4 steps every 512 pixels ending in 188
•
Grey Horizontal Ramp
o
2 horizontal ramps starting at 0 increases in by 1 every 32 pixels
•
Grey Vertical Ramp
o
Vertical ramp starting with blue 5, green 12, red 19, and incrementing by 3 every
line
•
Grey Diagonal Ramp
o
Add horizontal and vertical ramps
•
User Pattern
o
When selected, the camera will first output all pixels values to be half full scale. The
user can then generate a custom test pattern by uploading PRNU coefficients that
appropriately manipulate the half scale data to achieve the desired pattern. See
section Setting Custom Flat Field Coefficients for details.
