A Novel Scan-Converting Oscillographic Technique for In-Situ Signal Acquisition with Subsequent Automatic Digitization

摘要

This report discusses the development of a novel equipment for the remote acquisition of oscillographic data in the form of a scan-conversion television signal, its temporary storage by means of an inexpensive video tape recorder, and its subsequent digitization. The essential feature of this equipment is its property of scan conversion: signals captured by a Tektronix R7912 Transient Digitizer are read out not in digital form, but rather as television images of the acquired traces, recorded at the site of the experiment, and returned to the laboratory for subsequent digitization and processing.
