Abstract
A system for sequentially refreshing segments of the stored voltage characteristics of electron guns includes a clock gate. The clock gate passes clock pulses to a counter which refreshes the stored voltage signals. After a predetermined number of counts, the counter inhibits the clock gate until a vertical blank pulse enables the clock gate and the counter resumes counting.
