Most video signals have an output impedance of 75 Ω. The channel inputs of the
R&S RTE have an input impedance of 50 Ω or 1 MΩ. Make sure to provide the ade-
quate matching to ensure amplitude fidelity. A simple 75 Ω feed-through termination
combined with 1 MΩ oscilloscope inputs is suitable for most applications.
Once the trigger is set correctly, you can use cursor and automatic measurements to
perform amplitude and timing measurements.
