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 can measure the input supply voltage at the power connector and the internal
temperature. Both of these features are accessed using the Camera CamExpertGUI > Camera
Information tab. Press the associated refresh button for 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 00H increases in by 01H every 32 pixels.
 Grey Vertical Ramp
o
Vertical ramp starting with 1
st
row 5, next row 12, 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.
Built-In Self-Test Codes
The Built-In Self-test (BIST) codes are located in the Camera Information pane under Power-on
Status. None of these should occur in a properly functioning camera except OVER_TEMPERATURE.
OVER_TEMPERATURE occurs if the ambient temperature is too high, there is insufficient air
circulation or heat sinking.
