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 these keys to navigate through captured data via time, search
events, or segmented memory acquisition. See “Navigating the Time Base" on
page 75.
For more information see Chapter 2 , “Horizontal Controls,” starting on page 63.
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 215.
9. [Default Setup] key Press this key to restore the oscilloscope's default settings (details on “Recall the Default
Oscilloscope Setup" on page 33).
10. [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 34.
