Ground Coupling
Used to display a zero-volt waveform. Internally, the channel input is connected with a zero-volt
reference level.
Fine Resolution
In the fine resolution setting, the vertical scale readout displays the actual VOLTS/DIV setting. The
vertical scale changes only after you adjust the VOLTS/DIV control and set to coarse.
Remove Waveform Display
To remove a waveform from the screen, first push the menu button to display the vertical menu,
then push again to remove the waveform. A channel waveform which is unnecessary to be
displayed can be used as a trigger source or for math operations.
3. VOLTS/DIV Knob

Settings Comments
DC passes both DC and AC components of the input
DC AC signal.
Ground AC blocks the DC component of the input signal and
attenuates signals below 10Hz.
Ground disconnects the input signal.
Limits the bandwidth to reduce display noise; filters the
Unlimited
signal to eliminate noise and other unnecessary HF
Limited
components.
Selects the resolution of the VOLTS/DIV knob.
Coarse
Coarse defines a 1-2-5 sequence. Fine changes the
Fine
resolution to small steps between the Coarse settings.
1X
Selects a value according to the probe attenuation factor
10X
so as to ensure correct vertical readouts. Reduce
100X
bandwidth to 6MHz when using a 1X probe.
1000X
Off
Inverts the waveform relative to the reference level.
