Time/Div.
The "Time/Div." wheel determines, how long the electronic
beam which draws the curve needs for moving from the left to the right edge
of a division. The wheel controls the "time scale". A "division" is one
square on the screen of the oscilloscope.
If the wheel is set to "1 ms" for example, it means that 1
ms is needed per square for the horizontal movement, i.e. 10 ms for moving
the beam from the left to the right edge of the screen, because the surface
is divided into 10 divisions. "Surface" in this regard means the whole
movement range of the beam, because in "X-Mag."
mode the surface is stretched 10 times its original size.
The horizontal frequency in that example would be 1/1 ms =
1000 Hz, this means the electronic beam moves 1000 times a second from the
left to the right edge of the screen. The observer sees an image that seems
to be continuous, non-flickering. In longer "Time/Div." settings however the
movement of the electronic beam becomes visible. In the simulation longer
"Time/Div." settings can only be displayed with some quality restrictions as
the calculation power of the
Macromedia
scripting language "Lingo"
in connection with current processor speeds is not enough to perform the
full realtime calculation.

The "Time/Div."
wheel is made up of two wheels: The big wheel
is a coarse setting of previously calibrated values. To obtain the
calibrated values, the small wheel rotation must be set to its left edge. |

With the small wheel, located on top of the big wheel, a
fine adjustment can be made. The small wheel is only calibrated for its
leftmost position. |
