摘要: The requirements of a time-base suitable for low and intermediate speeds are discussed with special reference to the use triggered multiple sweeps. A slow sweep having fast flyback is described. Sweep durations from 100 sec. 10 msec. available duration 1/1000th part scan time. Higher speeds, up 50 μsec. (20 kc/s), may be obtained but less favourable ratios. will self-run or initiated externally single circuit direct-coupled throughout, linear traces identical velocity generated irrespective nature triggering wave. unaffected by any trigger pulses which occur whilst spot sweeping. Trace brightening provided ractified output an r.f. oscillator: if required, this oscillator also modulated give timing markers.
