Dots
Small pin points developed at the intersection of the H bar and V bar elements,
especially for linearity measurements with the EIR linearity (ball) chart.
Resolution
Square wave bar pattern at selected repetition rate to develop desired resolution tv
lines in ten increments (usually 100 to 1000 lines at 100-line steps), at full, 100%
black-to-white contrast. Presented as continuous, burst or multiburst. Reference
bars are also selected over entire tv field.
(2) Operating Modes:
Pattern polarity Selection of either white-on-black or black-on-white patterns for bar, dot, window and
related functions.
Internal preset calibration for automatic selection of pattern proportion for the 675/60
scan rate. Variable front panel adjustment for certain patterns.
