Basic Operation
DSO8000E Series HandHeld Oscilloscope User Manual 18
5.2.1 Scan Mode Display (Roll Mode)
With the TIME/DIV control set to 80ms/div or slower and the trigger mode set to Auto, the
oscilloscope works in the scan acquisition mode. In this mode, the waveform display is updated
from left to right without any trigger or horizontal position control.
5.3 Vertical Controls
Vertical controls can be used to display and remove waveforms, adjust vertical scale and position,
set input parameters and perform math calculations. Each channel has a separate vertical menu
to set. See below for menu description.
1.
VERTICAL POSITION Bar:
Move the channel waveform up and down on the screen. In
dual-window mode, move the waveforms in both windows at the same time in a same direction.
Two channels correspond to two bars.
2.
Menu (CH1, CH2):
Display vertical menu options; turn on or off the display of channel
waveforms.

Comments
Coupling
DC
AC
GND
DC passes both DC and AC components of the input
signal.
AC blocks the DC component of the input signal and
attenuates signals below 10Hz.
Ground disconnects the input signal.
20MHz Bandwidth
Limit
Unlimited
Limited
Limits the bandwidth to reduce display noise; filters the
signal to eliminate noise and other unnecessary HF
components.
Volt/Div
Coarse
Fine
Selects the resolution of the VOLTS bar.
Coarse defines a 1-2-5 sequence. Fine changes the
resolution to small steps between the Coarse settings.
Probe
1X
10X
100X
1000X
Selects a value according to the probe attenuation
factor so as to ensure correct vertical readouts. Reduce
bandwidth to 6MHz when using a 1X probe.
Invert
Off
On
Inverts the waveform relative to the reference level.
Reset
Set the channel vertical postion to the middle of the
vertical screen,
