  • Page 48: Checking Gamut

    Checking Gamut Checking Gamut Signals that are legal and valid in one signal representation may not be legal in another representation. Specifically, signals which are legal in the Digital YCbCr representation may not be legal if transcoded to RGB or encoded to NTSC/PAL. Any signal that fails this test is considered outofgamut.

  • Page 51: Checking Composite Gamut

    Checking Gamut Checking Composite Gamut The Arrowhead gamut display plots luminance (Y) against chrominance (C) to check if the composite signal adheres to standard gamut. NTSC and PAL Arrowhead displays (75% Color bars) show the values of the graticule lines. The arrowhead shape of the graticule results from overlaying the standard limits for luminance and luminance-plus-peak chrominance.

    Timing Display Timing Display The Timing display is a Tektronix proprietary display that simplifies measuring the timing difference between two signals as the timing is corrected. You can access this display from the STATUS button. Using the Timing display enables you to easily compare and correct the timing between two signals.
  • Page 56 Timing Display Timing Pop-up Menu Once you have selected Timing Measure from the STATUS button pop-up menu, pop-up menu enables you to save a timing setting for comparison with another signal and specify the zero point of the timing display. To save the timing of the current input as an offset to the timing display, use the Save Offset menu entry.

Non-integer multiples of reference rates. If you time input rates that are not integer multiples of the reference rates, the instrument cannot measure the timing deterministically, so it displays the relationships as several circles.
