3.11 Generating a Test Pattern
The Falcon camera includes a built in test pattern generator that can be used to confirm camera
connections or driver installations, without the need for a camera lens or proper lighting. The pattern
generator inserts video just after the sensor A/D converter, therefore Falcon processing such as the LUT
act on the generator images or on sensor images.
Serial Command:svm
Purpose: Generates a test pattern to aid in system debugging. The
test patterns are useful for verifying proper timing and
connections between the camera and the frame grabber.
The following table shows each available test pattern.

When switching the camera from video mode (svm 0) to
one of the test pattern modes (svm 4 thru 8), the camera
"turns off" any digital gain (
ssg), and background
subtract (
ssb) settings currently being used. The gcp
screen
does not turn off these settings and displays the
settings used prior to switching to test pattern mode.
When returning to video mode (svm 0), the digital gain,
background subtract and exposure control settings are
returned to their prior state.
Example:
• svm 5
