*
Set the measurement window in an area where the average video level is uniform. If you include dark
areas in the video caused by the effect of the lens or areas where the video signal of the object is not
flat, accurate video noise measurement may not be possible.
*
There may be cases in which accurate video noise measurement is not possible due to overshooting,
undershooting, or ringing occurring in the rising or falling edges of the waveform depending on the
input video signal. If this happens, set the measurement window a few percent inside of the rising or
falling section.
