Effective bandwidth is 6 MHz with a P2220 probe set to 1X.
The option for voltage and current probes is different: Attenuation or Scale.

Knobs
Vertical Position Knobs.
Use the
Vertical Position
knobs to move the channel
waveforms up or down on the screen.
Vertical Scale (volts/division) Knobs.
Use the
Vertical Scale
knobs to control how
the oscilloscope ampli
fi
es or attenuates the source signal of channel waveforms.
When you turn a
Vertical Scale
knob, the oscilloscope increases or decreases the
vertical size of the waveform on the screen.
Vertical Measurement Overrange (Clipping).
A display of
?
in the measurement
readout indicates an invalid value. This may be due to waveforms that extend
beyond the screen (overrange). Adjust the vertical scaling to ensure the readout
is valid.
Key Points
Ground Coupling.
Use Ground coupling to display a zero-volt waveform.
Internally, the channel input is connected to a zero-volt reference level.
Fine Resolution.
The vertical scale readout displays the actual volts/division
setting while in the
fi
ne resolution setting. Changing the setting to coarse does not
change the vertical scale until the
Vertical Scale
control is adjusted.
