4.5 Operation Panel
(1) Vertical Control
① CH1 、 CH2 ：Analog channel setting keys, CH1, CH2 identified by different
colors and it also corresponding to the colors of waveforms on the screen and
channel input connectors. Press any key to turn on the related channel menu
(activate or disable channel).
② MATH ：Press this key to open the mathematical operation menu for add,
subtract, multiply, divide, FFT, logical operations, digital filtering and advanced
operations.
③ Vertical POSITION ：Adjust the vertical position to move the current channel
waveform, the vertical offset value will display at the baseline cursor.
Press this knob to return the channel display back to the vertical midpoint.
④ Vertical SCALE ：Vertical position knob is used for adjusting the vertical scale,
turn clockwise to decrease the scale, turn counterclockwise to increase the scale.
With this process, waveform will display increasing or decreasing and position
information will also be presented at the same time. The vertical
scale stepped as 1-2-5 order. Press the knob allows the vertical adjustment to
switch between coarse and fine adjustment mode.
(2) Horizontal Control
① HORI MENU ：Horizontal menu is for display window extension, Multi-

parameter will display on the top of the screen in real- time. Press
this knob to return the channel display back to the midpoint position.
③ Horizontal SCALE ：Used to adjust the time base of all the channel. Screen
will display the changes of the waveform, compressed or extension on
horizontal. Time base will display on the top of the screen in
real- time. The time base scale stepped as 1-2- 5 order. Press the knob
