niVMS Analyse Camera VI
Performs an analysis of the composite signal output by an analog CCD camera. Each type of measurement yields several video parameters that are displayed in the Results array (including name, value, and units). A graph of a relevant output waveform is displayed for most measurements and can be used for signal and measurement verification.
IMPORTANT NOTES:
- Before running this VI, ensure that desired video standard is configured, that video lines containing the appropriate test patterns have been acquired, and that the line selection made here matches accordingly. Failure to do this results in invalid measurements or a run-time error.
- Auto iris timing and external sync AC measurements require the digitizer to be specially configured for acquisition of nonvideo signals.
