How to Set the Vertical System

The VERTICAL CONTROLS includes 5 menu buttons such as CH1 - CH4
and Math, and 8 knobs such as VERTICAL POSITION, VOLTS/DIV for each
channel.
Setting of CH1 - CH4
Each channel has an independent vertical menu and each item is set respectively
based on the channel.
To turn waveforms on or off (channel, math)
Pressing the CH1 - CH4 or Math buttons have the following effect:
• If the waveform is off, the waveform is turned on and its menu is displayed.
• If the waveform is on and its menu is not displayed, its menu will be displayed.
• If the waveform is on and its menu is displayed, the waveform is turned off and
its menu goes away.
The description of the Channel Menu is shown as the following list:

1. To set channel coupling
Taking the Channel 1 for example, the measured signal is a square wave
signal containing the direct current bias. The operation steps are shown as
5.Advanced User Guidebook
Description
DC Pass both AC and DC components of the input signal.
AC Block the DC component of the input signal.
Ground Disconnect the input signal.
Select the input impedance to use. When 50Ω is
1MΩ
selected, AC in coupling is not available. If the
impedance is set to 50Ω when using AC coupling, the
50Ω
coupling will be set to DC automatically.
ON Display inverted waveform.
OFF Display original waveform.
X1
X10 Match this to the probe attenuation factor to have an
X100 accurate reading of vertical scale.
X1000
Full Get full bandwidth.
20M Limit the channel bandwidth to 20 MHz to reduce
display noise.
