• SYNC SIGNAL means the voltage of the synchronic signal; user can use this
signal to evaluate the impedance of coaxial cable. For example, if the
synchronic signal number of camera is 0.3V (tested by tester in the camera side),
after a long distance transmission via coaxial cable, the synchronic signal
number falls to 0.21V (tested again by tester ), this means the attenuation of
video signal via this coaxial cable is 30%. User can evaluate if the quality of
coaxial cable is good enough for this distance’s usage.
• If there is no signal is detected, “No Video” will be displayed.
