2.7 Horizontal System
As follow Picture, there are one button and two knobs in the HORIZONTAL area.

Two Cursors define one window; use horizontal POSITION
and S/div to adjust the window.
Window
Change the display so that the waveform could be displayed
in the window(expanded to screen width).

Introduction
The axis of the vertical scale is GND level. The readout on the top right corner,
which unit is sec, show us the horizontal position. M Mean main time base, W
mean window time base.. It is also a arrow on the scale top to show the vertical
position.
■ Window Zone:
Using Window Zone to define one wave sect, it is useful to reap the details. The
Window time base setting cannot be set slower than the Main time base setting.
■ Window:
Expand the window to cover the whole screen.
2.7.1 Horizontal control knob
You can use the horizontal controls to change the horizontal scale and position of
waveforms. The horizontal position readout shows the time represented by the
center of the screen, using the time of the trigger as zero. Changing the horizontal
scale causes the waveform to expand or contract around the screen center.
■ Horizontal POSITION knob
1. Adjust the horizontal position of all channels and math waveforms (the
position of the trigger relative to the center of the screen). The resolution of
this control varies with the time base setting.
2. When you press the horizontal POSITION Knob, you can set the
horizontal position to zero.

Turn on this function that main timebase
waveform display on the top half screen and
window timebase wavefrom display on the
below half screen at the same time.
Turn off this function that only display main
timebase waveform on the screen.
MemDepth

Long MemSet
memory depth to normal.
Set memory depth to long Memory depth in
order to get more waveform dots.
■ HORI MENU button:
Press the HORI MENU button to display the horizontal Menu. In this menu,
you can turn window mode on or off. Otherwise, you could set the horizontal
position knob to Trig-offset.
Note
1. Only some series model DSO support Long Memory
2. If set memory depth to nomal mode, the momory depth is 40Kpts
2. If set memory depth to LongMem mode, the momory depth is 2Mpts
