, Off Limits the bandwidth to reduce display noise;
filters the signal to reduce noise and other
unwanted high frequency components
Volts/Div Coarse, Fine Selects the resolution of the Scale (Volts/Div)
knob
Coarse defines a 1-2-5 sequence. Fine changes
the resolution to small steps between the coarse
settings
Probe See the next table Push to adjust Probe options
Invert On, Off Inverts (flips) the waveform with respect to the
reference level
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 amplifies 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.

Effective bandwidth is 6 MHz with a P2220 probe set to 1X.
