Use the procedure that follows to take cursor measurements on waveforms.
Overview To take cursor measurements Related control elements and resources
Prerequisites 1. At least one waveform must be selected on screen. Or

4. Turn the General Purpose knob to position each cursor
on the waveform to measure the feature that interests
you.
5. Read the results in the cursor readout.
In the figure shown above, waveform cursors are
used to measure the bit-time of the eye diagram.
Tip. The cursor readout indicates the source time
base and waveform for the selected cursor; in this
case, the main time base, M1, and channel 1, C1.
