4-5-6. Limit Bandwidth
Background
Bandwidth limitation puts the input signal into a
selected bandwidth filter.
This function is useful for cutting out high
frequency noise to see a clear waveform shape.
The bandwidth filters available are dependent on
the bandwidth of the oscilloscope model.

4-5-7. Expand by Ground/Center
Background
When the voltage scale is changed, the Expand
function designates whether the signal expands
from the center of the signal or from the signal
ground level. Expand by center can be used to
easily see if a signal has a voltage bias. Expand by
ground is the default setting.
