Effective bandwidth is 6 MHz with a P2220 probe set to 1X.
The option for volta

Knobs
Vertical Position Knobs. Use the Vertical Position knobs to move the channel
waveformsupordownonthescreen.
Vertical Scale (volts/division) Knobs. Use the Vertical Scale knobs to control how
the o scilloscope amplifies or attenuates the source signal of channel waveforms.
WhenyouturnaVerti ca l S cale knob, the oscilloscope increases or decreases the
vertical size of the waveform on the screen.
Vertical Measurement Overrange (Clipping). Waveforms that extend beyond the
screen (overrange) and display a ? in the measurement readout indicates an
invalid value. 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 fine resolution setting. Changing the setting to coarse does not
change the vertical scale until the Vertical Scale control is adjusted.
