Controlling The Timing Display
1 . Move the cursor to the Magnification field in the Timing Waveform Diagram .
2. Press the NEXT[] key to obtain 4X magnification . This shows a window in the timing memory . One-
fourth of the memory is on screen .
3. Press the ROLL down key to see the window move through the timing memory (display moves across
the screen) .
4. Press the NEXT[] key several times to see the magnifications available . Select a magnification factor
that leaves several waveform transitions on screen .
5. Press and hold the CURSOR right key until the "x" marker moves out onto the display area . Place the "x"
marker on one of the waveform transitions on the display. The first line above the waveforms on the
right-hand side of the screen shows the measurement of time between the start of the memory and the
position where you placed the "x" (o to x) .
6. Press the NEXT[] key several times to see that magnification of the display occurs around the area in
memory you selected by the positon of 'Y' . See figure 6-3.
