ABSTRACT:
In a vacuum tube oscillscope for storing and reproducing electric signals, two matrices of charge transfer devices (CTDs) register and then reproduce the electric signals on a display screen. The two CTDs (21, 22) are juxtaposed at their sensitive areas (23, 24) without any interruption in accordance with a boundary which is substantially perpendicular to the time base deflection. The CTDs are scanned in accordance with trace and retrace write scan sequences. This facilitates reproducing the electric signals with pre-triggering.
