Setup Step View the Input Signal (Optional)
The VIEW INPUT hardkey allows you to look at the input signal before it is filtered to a reduced
frequency span, triggered, or measured. These instantaneous displays can be viewed at any time,
even if the measurement is in progress, waiting for a trigger, or completed. Instantaneous displays
can be used to verify the presence of input signals or to compare an input signal with a measurement
display. Instantaneous displays are also helpful when manually setting the input range. Chapter 2,
"Measurement Overview," explains how these displays are derived and how they differ from
filtered-input and measurement displays. In time capture mode, VIEW INPUT uses the HANN
window.
The softkeys that appear when you press VIEW INPUT depend on which measurement mode is
