This article describes a line and field signal generator for use with a pattern generator card to test a wide range of monitors. The line and field signals are produced by programmable counters connected serially in closed loops. The line is clocked by system clocks and provides clocks to the field card. The counters in the two sets are individually settable to define a range of line and field signals matching the requirements of the CRT device under test.
