Picture BRIGHT-UP
Now that pictures are created for high resolution displays and sometimes with high dynamic range luminance curve, we often receive the question about how to monitor carefully the levels in a video signal directly in the picture. There many ways to measure that and some are well known: Luminance Vector display (see T&T N°109), Diamond display, Spearhead display (see T&T N°66). But there is a particular display for long long time, in all Tektronix oscilloscopes that allows to check very rapidly the level of luminance in the picture itself. This is the bright-up possibility that is switched off by default.
