RANGE keys
The vertical RANGE keys set the vertical scale (vertical sensitivity) of the selected
waveform.
In FFT mode, the RANGE keys set the scale for the amplitude range (y-axis) in the
spectrum display.
In "Counter" mode, the RANGE keys set the measurement range.
Remote command:
CHANnel<m>:SCALe on page 253

POS keys
Move the selected signal up or down in the diagram. The position is a graphical setting
given in divisions, while the offset sets a voltage.
You can also drag the channel marker on the screen.

2.2.2 Effect of the Bandwidth Filter
Low-pass filters reduce the speed of the signal inside the instrument and cause a delay
of the signal on the screen. The delay time depends on the selected filter.
The following table lists the approximate delay of the signal that is caused by various
filters.
