Trigger problems
The non-interlaced trigger circuits expect synchronization
pulses that comply with standard video, or that are of
similar amplitude but with shorter pulsewidth. The circuit
however covers most other “standards” too. In case of
incidental problems you always can define the trigger
conditions in more detail using the time qualified pulse
triggering.
