or Hex mode. Press the Cursors hardkey (in the Measure section), then press the

Mode softkey to select Binary. The X1 and X2 cursors are positioned in the display

below to show the logic values of 0111 just before the trigger point, and 1000 just after

the trigger (the time base was changed to 10 ms/div for clarity). Try Hex mode as well.
