Waveform Generator (625 lines). Similar to GEl/520 but
without fixed oscillator supply changeover and battery
stabiliser. From an input signal at Natlock reference
frequency it produces a phase controlled output signal at
twice line frequency to drive a sync pulse waveform
generator. PN3A/16E with UN17/50l, UN17/S02, UN17/5l8,
PS2/l3F.
