Diagnostic Tools
Camera Data File
The Camera Data file includes the operational configuration and status of the camera plus a record
of recent commands sent to the camera along with status responses. 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 Piranha XL 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.
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 08H increases in by 10H steps every 1K pixels ending in F8H except first
and last 16 pixels are 01H
•
Grey Horizontal Ramp
o 64 horizontal ramps starting at 00H increases in by 01H every pixel ending in FFH
except first and last 16 pixels are 01H
•
Grey Vertical Ramp
• Grey Diagonal Ramp
• 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.
Note. Items in italics are specific to the internal hardware of the camera and will only be useful to
the User when communicating potential issues with Teledyne DALSA technical support team.
