Front-Panel Operation
This section provides a brief overview of operating the
front-panel controls. Detailed oscilloscope operating
instructions are provided in later chapters.
To adjust the waveform intensity
The Intensity control is at the lower left corner of the front
panel near the power switch.
• Rotate the Intensity control clockwise to increase the intensity
of displayed waveforms, or counter-clockwise to decrease
intensity. For more information see “Varying the intensity to
view signal detail” on page 208.
To adjust the display grid (graticule) intensity
1 Press the Display key.
2 Turn the Entry knob to change the intensity of the
displayed grid. The intensity level is shown in the Grid softkey
and is adjustable from 0 to 100%.
Each major vertical division in the grid corresponds to the
vertical sensitivity shown in the status line at the top of the
display.
Each major horizontal division in the grid corresponds to the
sweep speed time shown in the status line at the top of the
display.
To start and stop an acquisition
• When you press the Run/Stop key, it illuminates in green and
the oscilloscope is in continuous running mode.
The oscilloscope examines the input voltage at each probe,
and updates the display whenever the trigger conditions are
met. Trigger processing and screen update rate are optimized
based on the oscilloscope settings. The oscilloscope displays
multiple acquisitions of the same signal similar to the way an
analog oscilloscope displays waveforms.
