RASTER_VERTICAL_TRIGGERING_GENERATOR
Output pulse width of blocking oscillator Q1 is over 3.5 microsec, determined by T1 and C2.Q2 couples this pulse to output H for use as unsynchronized output, while 03 with 400-kc sync input serves with D2 as coincidence gate to give output only when both sync and gate pulses are present-R.
