H Press CURSOR.
H Press the main-menu button Function; then press the side-menu
button V Bars.
H Press CLEAR MENU.
H Align one V bar cursor to the time reference point of the left-most
waveform edge and the other cursor to the time reference point of the
right-most waveform edge by rotating the General Purpose knob.
(Press SELECT to switch between the two cursors). See Figure
1–11 on page 1–44.

g. Check against limits: CHECK that the cursor readout on screen is
≤100 ps for the TDS 600B or ≤50 ps for the TDS 500D/700D.
h. If the channel skew is within the limits, enter time on the test record and
proceed to step 3. Otherwise, proceed with steps i through p.
