G09G 1/08

the beam directly tracing characters, the information to be displayed controlling the deflection as a function of time in two spatial co-ordinates, e.g. according to a cartesian co-ordinate system

Introduced: January 1980

Full Title

Full titles differ between systems:

IPC:

Control arrangements or circuits, of interest only in connection with cathode-ray tube indicators > using single beam tubes > the beam directly tracing characters, the information to be displayed controlling the deflection as a function of time in two spatial co-ordinates, e.g. according to a cartesian co-ordinate system

CPC:

Control arrangements or circuits, of interest only in connection with cathode-ray tube indicators; (cathode-ray oscilloscopes G01R13/20; ) > using single beam tubes (G09G1/26, G09G1/28 take precedence), > the beam directly tracing characters, the information to be displayed controlling the deflection as a function of time in two spatial co-ordinates, e.g. according to a cartesian co-ordinate system

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 1980.
