Tektronix TBS1052B User Manual

Triggering on a video signal
You are testing the video circuit in a piece of medical equipment and need to
display the video output signal. The video output is an NTSC standard signal.
Use the video trigger to obtain a stable display.
NOTE. Most video systems use 75 ohm cabling. The oscilloscope inputs do not
properly terminate low impedance cabling. To avoid amplitude inaccuracy from
improper loading and reflections, place a 75 ohm feedthrough terminator
(Tektronix part number 011-0055-02 or equivalent) between the 75 ohm coaxial
cable from the signal source and the oscilloscope BNC input.
