the two cursors. The active cursor is the solid cursor.
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.
