    75% or 100% color bar signals. NOTE. Refer to the reference document A Guide to Standard and High-Definition Digital Video Measurements at the Tektronix, Inc. Web site (www.tektronix.com) for information about how the Vector and Lightning displays are created.
  • Page 90 Lightning display to quantify the amount of timing error. The Lightning display is a Tektronix, Inc. proprietary display combining a vertical luminance axis with horizontal chrominance information. The Lightning display plots the color difference signals, Pb and Pr, with the luminance (Y) signal.

  • Page 92 Reference Luminance Gain Measurement. The signal is driven along the vertical axis above and below the center box by the luminance signal. The luminance gain is correct when the center dot (clamped black level) is centered in the target box and the positive and negative excursions end at the top and bottom of the graticule.

    Reference Waveform Mode Press the WFM button to enter the Waveform mode. In Waveform mode, the selected components are displayed in a voltage versus time plot. You can apply flat or low pass filters and choose the color space modes (such as RGB or composite).
  • Page 94 Sweep. Use the Sweep menu to select from the following sweep modes: H Line. One horizontal line is displayed. Use the Line Select function to H 2 Line. (Overlay mode only) Two consecutive horizontal lines are displayed. H Field. All lines for one video field are displayed. H 2 Field.
  • Page 95 Reference Measuring Relative Timing To measure the timing of two digital signals, use the following procedure: Between Two Serial 1. Connect the two terminated SDI signals to be measured to Input A and Component Signals 2. Select Input A to display on the waveform monitor. 3.
