Measuring with Cursors
Overview
Cursors are important tools that help when measuring signal values. Cursors can
be moved around on the waveform to identify specific voltage and time values on
the waveform. Use cursors to make fast, accurate measurements and to eliminate
guesswork.
The cursor controls contain two dedicated cursor knobs and a Type button. The
Type button turns cursors ON (if they are not already ON), then toggles between
Horizontal (Time) cursors, Vertical (Amplitude) cursors, and OFF. If an FFT Math
trace is ON, a Horizontal (Frequency) selection is added to the toggle list.
When cursors are ON, they provide measurements for every waveform displayed.
The lone exception is when a Math FFT is ON, which requires a selection of
Horizontal (Frequency) for cursors to be placed on that waveform. Place cursors
on a Zoom waveform by moving the cursors into the zoom portion of the original
channel signal.
