Figure 3-3. Full-Screen Waveform Graticule
Figure 3-4 shows an unzoomed, full-screen vector display graticule with no signal
displayed. INPUT A has been selected, and the REF is internal. The signal standard is
NTSC. The STATUS is not ON AIR, and the SOURCE ID has been set to read
INPUT A. The SC/H phase is measured to be 0°. Red, Magenta, Yellow, Blue,
Green, and Cyan are targets for a color bar test pattern and the horizontally indicated
area in which the back porch color burst should fall.
Figure 3-4. Unzoomed Full-Screen Vector Display
Figure 3-5 shows an unzoomed full-screen audio levels display with audio signals
present. Audio channel A has been selected, and the 0 marks on the vertical scales
correspond to the audio reference of +8 dBm. The STATUS is not ON AIR, and the
SOURCE ID has been set to read INPUT A. The SC/H phase is measured to be 0°.
The instantaneous level of audio source L1 is about 0 dB, and that of audio source R1
is +12 dB or more. L2 and R2 levels are about +8 and +1 dB. The phase differences
between L1 and R1, and L2 and R2 are each less than 90°.
