Timing Measure display
The Timing Measure display a Tektronix proprietary display that simplifies
measuring the timing difference between the SDI video input signal and the
analog video external reference signal as the timing is corrected. This display
enables you to easily compare and correct the timing between two signals.
For this display to operate, signals must be connected to the selected video input
and to the external reference input. Use the Waveform display to view the video
input waveform and use the External Reference Waveform display to view the
external reference signal. See also
