14 . Press the CURSOR right key and hold it to move the "o" out on the display . Notice the time measurement
indication change as the "o" moves closer to the "x".
15 . Place the "o" marker on another waveform transition on the display.
16 . The time measurement indication on the display will show you the measure of time between the two
waveform transitions you selected using the "x" and "o" markers.
17 . With the cursor in the Cursor Moves field, press the NEXT[] key to obtain the [x&o] indication . With this
selection, the "x" and "o" markers will move together and maintain a constant interval between them .
You can use these two markers together to compare intervals between any two points of interest on the
display.
18 . Move the cursor into the Magnification field and use the NEXT[] key to obtain a X1 display.
19 . Use the CURSOR right and CURSOR left keys to move the "o" and "x" markers togetherto another set of
waveform transitions on the display.
20 . Place the "x" marker on one of the waveform transitions .
21 . Move the cursor down into the Cursor Moves field and press the PREV[] keyto select Cursor Moves [o].
22 . If the events are not the same distance apart as the first set, use the CURSOR keys to move the "o"
marker alone. You can measure the dimension between the two new waveform transitions.
23 . Press the CURSOR left and CURSOR right keys . Notice that the "o" marker can cross the "x" marker,
and the measurement indication above the traces will correct itself (show "x to o" or "o to x") .
Selecting Trace Positions On The Display
1 . Press the CURSOR down key to move the cursor into the B5 field .
2. Press the PREV[] key several times. You can place any of the bits from the timing memory at any location
on the display. You can also turn off a display channel, if desired .
3. Press the DELETE key several times. You can eliminate channels from the display, if desired. Note that
the vertical display is magnified when eight or less channels are on screen .
4. Press the INSERT key several times. You can add channels to the display, up to a maximum of 16
channels in non-glitch mode and 8 in glitch mode . See figure 6-4 .
5. Press the blue SHIFT key and DEFAULT . This restores all channels in the display to their original
