In normal display mode, with vectors (connect- the- dots) off, you can scale
in to the point where there are no samples on the screen. Obviously, this
is far beyond the useful limit. Likewise, with vectors on, you can see the
linear interpolation between the points, but again, this is of very limited
value.
Zooming into stopped acquisitions
N O T E
The screen will still contain a relatively good display if you zoom-in horizontally by a factor
of 1000 and zoom-in vertically by a factor of 10 to display the information from where it was
acquired. Remember that you can only make automatic measurements on displayed data.
To change the horizontal time mode (Normal, XY, or Roll)
1 Press [Horiz].
2 In the Horizontal Menu, press Time Mode; then, select:

Normal — the normal viewing mode for the oscilloscope.
•
In the Normal time mode, signal events occurring before the trigger
are plotted to the left of the trigger point (t) and signal events after
the trigger plotted to the right of the trigger point.
XY — XY mode changes the display from a volts- versus- time display
•
to a volts- versus- volts display. The time base is turned off. Channel 1
amplitude is plotted on the X- axis and Channel 2 amplitude is
plotted on the Y- axis.
You can use XY mode to compare frequency and phase relationships
between two signals. XY mode can also be used with transducers to
display strain versus displacement, flow versus pressure, volts versus
current, or voltage versus frequency.
Use the cursors to make measurements on XY mode waveforms.
For more information about using XY mode for measurements, refer
to
"XY Time Mode"
Roll — causes the waveform to move slowly across the screen from
•
right to left. It only operates on time base settings of 500 ms/div and
slower. If the current time base setting is faster than the 500 ms/div
limit, it will be set to 500 ms/div when Roll mode is entered.
