Burst will diminish in amplitude over longer cable runs and can fall
below the threshold required for the video display to show a color
image.
For NTSC, the standard chroma level is 40 IRE.
For PAL, the standard chroma level is 280 mV.
If the chroma level is too low, the color will not be as deep, and
some details of the image will become lighter. If the chroma level
is too high, there will be distortions in the image. If the coaxial
cable is too long, the chroma level will be diminished.
Image Loop Test:
Test the video’s optical transmitter, receiver and video cable.
Connect one end to the Tester’s Video Out port, and the other end
to the Video In port. The signal will be sent via the Video Out port,
and received via the Video In port. If testing is successful, the
Tester will display several gradually dwindling images on the
desktop.
