selected waveform as the measurement t arget .
Automatic Target Select ion for
Cursors
Yes Yes Yes If cursors are off, pushing the Cursor button on the front panel turns
cursors on w ith the sel ected waveform as thei r target.
Quick Horizontal Scale Adjust

horizontal scale t o fill the screen wi th the boxed portion (see
Quick-adjust the t ime base on page 3--63).
Graticules. One graticule is displayed for the Main time base, and an additional
graticule is displayed for each Mag time base that you turn on. Figure 3--16 on
page 3--54 shows the elements of the time base graticules; the elements are the
same for each time base displayed.
Using Multiple Views. The methods of displaying (turning on) and selecting any
time base view follow:
H Turn the view on: Press the Mag1 or Mag2 front-panel button once to turn on
the Mag1 or Mag2 time base. The Main view is always (displayed); you
cannot turn it off. Turning on a time base makes it active (selects it for
adjustment).
H Select among displayed views: Press any time base view button to make it
the active, selected time base. The button of the selected view is always lit
amber.
H Turn off the selected Mag view: Once selected, press the Mag1 or Mag2
button to turn off the time base. The Main time base becomes the selected
time base.
Operations on the Selected Time Base View. The method of adjusting (horizontal
scaling and positioning, setting resolution/record length, and so on) is from the
front panel: select the time base using the Horizontal time base selection buttons,
