I managed to show on my scope a symbol formed by several dots by controlling voltages at the X-Y axis.
To make it neat I would need to blank the retrace between dots.
My scope is an old analog TRIO 10 MHz CS1562A. Couldn't find the manual but a PDF version found in the Web says that "modulation" may be done "at TTL" levels.
Just in case, I tried myself bringing the Z axis input to 0V and 5V, getting only a change in brightness.
Is it any way I could blank completely the retrace in between spots?
