ABSTRACT:
An operation display method and apparatus for variables of an oscilloscope including a rotary-push mechanism connected with a rotary knob is disclosed. When the rotary knob is rotated clockwise a little, a right directional arrow is displayed on a CRT. Then e.g. a cursor is shifted to the right on the CRT by a division every pushing the rotary knob. When the rotary knob is rotated clockwise or counterclockwise, the cursor is shifted a little to the right or the left. When the knob is rotated counterclockwise in the precise adjustment, a left directional arrow is displayed on the CRT. Then the cursor can shifted to the left on the CRT by a division every pushing the knob. Other variables can be operated in the same manner.
