Vertical offset is unavailable for channel waveforms displayed with rho
Vertical Offset
Yes
No
No
Vertical offset is unavailable for channel waveforms displayed with rho
or ohm units.
Horizontal Scale
Yes
No
No
All channel waveforms are adjusted globally in the selected time base.
Math waveforms are not adjusted because their horizontal parameters
Horizontal Position
Yes
No
No
Math waveforms are not adjusted because their horizontal parameters
are derived from their sources. Reference waveforms are not adjusted
because they have fixed horizontal parameters determined at the time
Horizontal Record Length
Yes
No
No
because they have fixed horizontal parameters determined at the time
the waveform was saved.
Automatic Source Selection
for Automatic Measurements
Yes
Yes
Yes
Measurements, if selected from Measurements toolbar, use the
selected waveform as the measurement target.
Automatic Target Selection for
Cursors
Yes
Yes
Yes
If cursors are off, pushing the Cursor button on the front panel turns
cursors on with the selected waveform as their target.
Quick Horizontal Scale Adjust
(Zoom)
Yes
No
No
Dragging a box around a portion of the selected waveform adjusts
horizontal scale to fill the screen with the boxed portion (see
Quick-adjust the time 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,
