ABSTRACT:
A signal sampling and conversion system for high-frequency sampling of either recurrent or non-recurrent signals in which the electron beam (9) generated by an electron gun (1) of a CRT is scanned across a target semiconductor integrated-circuit (4) comprising a linear array of tapered detection and storage elements in two opposing groups represented by elements (5an) and (5bn), connected respectively to parallel-to-serial convertors (7a) and (7b). The sampling rate is proportional to the scan rate which is determined by the scan signal (11) applied to the deflection electrodes (3). The input signal (10) applied to a high-frequency deflection structure (2) causes charges to be accumulated in the elements of the array which are indicative of the amplitude or range of amplitudes of the input signal (10) during the period of each sample. The charges are removed from the array and converted to serial output data (14a) and (14b) which may then be processed to yield the amplitude of the input signal.
