5. [Default Setup]
key
Press this key to restore the oscilloscope's default settings (details on "Recall the Default
Oscilloscope Setup" on page 24).
6. [Auto Scale]
key
When you press the [Auto Scale] key, the oscilloscope will quickly determine which channels have
activity, and it will turn these channels on and scale them to display the input signals. See "Use
Autoscale" on page 24.
7. Horizontal and
Acquisition
controls
The Horizontal and Acquisition controls consist of:
• Horizontal scale knob — Turn the knob in the Horizontal section that is marked to
adjust the time/div setting. The symbols under the knob indicate that this control has the effect
of spreading out or zooming in on the waveform using the horizontal scale.
Push the horizontal scale knob to toggle between fine and coarse adjustment.
• Horizontal position knob — Turn the knob marked to pan through the waveform data
horizontally. You can see the captured waveform before the trigger (turn the knob clockwise) or
after the trigger (turn the knob counterclockwise). If you pan through the waveform when the
oscilloscope is stopped (not in Run mode) then you are looking at the waveform data from the last
acquisition taken.
• [Acquire] key — Press this key to open the Acquire menu where you can select the Normal, XY, and
Roll time modes, enable or disable Zoom, and select the trigger time reference point.
Also you can select the Normal, Peak Detect, Averaging, or High Resolution acquisition modes
and, on DSOX1200-Series models, use segmented memory (see "Selecting the Acquisition
Mode" on page 135).
• Zoom key — Press the zoom key to split the oscilloscope display into Normal and Zoom
sections without opening the Acquire menu.
For more information see Chapter 2 , “Horizontal Controls,” starting on page 37.
8. Run Control
keys
When the [Run/Stop] key is green, the oscilloscope is running, that is, acquiring data when trigger
conditions are met. To stop acquiring data, press [Run/Stop] .
When the [Run/Stop] key is red, data acquisition is stopped. To start acquiring data, press
[Run/Stop] .
To capture and display a single acquisition (whether the oscilloscope is running or stopped), press
[Single] . The [Single] key is yellow until the oscilloscope triggers.
For more information, see "Running, Stopping, and Making Single Acquisitions (Run
Control)" on page 129.
