Video and Testing: By default the Video will be displayed in the top portion of
the screen. If there is no video signal at the VIDEO IN port of the Rapport III
/Rapport HI-PRO "LOSS" will be displayed.
Depending on the type of camera connected to the tester the Video and Sync

PAL signals that are common throughout the rest of the world are measured in
mV (millivolts)
