PHASE ADJUSTING DEVICE FOR DISPLAY MONITOR

摘要

PURPOSE:To provide the phase adjusting device for a display monitor which measures a phase difference at constant rate without ancillary operations to light a raster, improves the accuracy and workability of adjustment and facilitates development for automation. CONSTITUTION:A phase measuring instrument 14 converts the time difference between the timing of the peak of the deflecting magnetic field generated from the display monitor 11 to be adjusted and the horizontal synchronizing signal from a signal generator 12 to digital data. A personal computer 15 has the constitution to display this digital data as graphics which are easily adjustable by an operator.
