1 Getting Started
7. Horizontal
controls
The Horizontal controls consist of:
• Horizontal scale knob — Turn the knob in the Horizontal section that
is marked to adjust the time/div (sweep speed) 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.
• 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.
• [Horiz] key — Press this key to open the Horizontal Menu where you
can select XY and Roll modes, enable or disable Zoom, enable or
disable horizontal time/division fine adjustment, and select the
trigger time reference point.
• Zoom key — Press the zoom key to split the oscilloscope
display into Normal and Zoom sections without opening the
Horizontal Menu.
•[Search] key — Lets you search for events in the acquired data.
•[Navigate] keys — Press this key to navigate through captured data
(Time), search events, or segmented memory acquisitions. See
“Navigating the Time Base" on page 60.
For more information see Chapter 2, “Horizontal Controls,” starting on
page 49.
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 187.
9. [Default Setup]
key
Press this key to restore the oscilloscope's default settings (details on
“Recall the Default Oscilloscope Setup" on page 31).
