X-Y OR Y-T DISPLAY MODE SELECTION
Press
to call up the display menu.
Press X - Y - to switch display modes.
X-Y mode displays Channel 2 (vertical) against Channel 1 (hori-
zontal) and Y-T mode displays both vertical channels against a hori-
zontal time base set by the SECIDIV switch.
In X-Y mode, the vertical position and horizontal position of the dis-
play is controlled by the Vertical POSITION knob. Select CH 2 to
position the display vertically and select CH 1 to position it hori-
zontally. X-Y is boxed in the menu list when that display mode is
selected and unboxed for Y-T mode.
The CH
1
and CH 2 traces are both turned on (if off) when X-Y mode is
selected, and they cannot be turned off while X-Y display mode is in
effect.

the readout may be turned off to unclutter the display. The readout is
controlled from the Display Mode menu.
