How to Scale Traces
The Scope window’s toolbar has Auto-Scale, Rescale, and Same Scale buttons to deal with changing signal
amplitudes.
Description Callout
Rescale 1
Auto-Scale 2
Same Scale 3
If the scope trace is off-scale (out-of-view) or too compressed, you can use the rescale feature to quickly
adjust the units/division and offset values to optimize the trace within the plot. The rescale feature scales the
trace to the minimum and maximum values of the data being acquired.
Once the trace is scaled to fit the plot, you can apply the auto-scale feature to automatically adjust the
units/division and offset of the plot to optimize the trace view.
Rescale control
Click the Rescale icon to immediately increase or decrease the scope’s Units/Div to accommodate the signal’s
amplitude.
• Once rescaled, Unit/Div changes to accommodate increasing signal amplitudes when Auto-Scale is on.
• Any manual adjustment that changes Unit/Div or Offset turns Auto-Scale off.
Note:
Pressing Rescale turns Auto-Scale on.
Auto-Scale control
Click the Auto-Scale icon to turn the feature on and off. When Auto-Scale is on, the scope increases the
Units/Div to accommodate increasing signal amplitudes.
• Auto-Scale accommodates increasing signal amplitudes but does not rescale the scope for decreasing
signal amplitudes.
• Use Rescale to accommodate decreasing amplitudes.
• To preserve Offset, click the Scope Setup icon. In the Scope Setup window, select Sensitivity in the
Auto-Scale Mode control.
