channel waveforms. When you turn the “volts/div”
knob, the oscilloscope increases or decreases the vertical
size of the waveform on the screen with respect to the
ground level.

When you press the “Volt/div” knob, you can switch
“Volts/div” option between “Coarse” and “Fine”. The
vertical scale is set by a 1-2-5 step sequence in Coarse
mode. Increase in the clockwise direction and decrease
in the counterclockwise direction. In Fine mode, the
knob changes the Volts/Div scale in small steps between
the coarse settings. Again, increase in the clockwise
direction and decrease in the counterclockwise direction.

Introduction
Coupling
DC
AC
GND
DC passes both AC and DC
components of the input signal.
AC blocks the DC component of the
input signal and attenuates signals
below 10 Hz.
GND disconnects the input signal.
BW limit
On
Off
Limits the bandwidth to reduce
display noise; filters the signal to
reduce noise and other unwanted
high frequency components.
