Acquisition and General Controls
Using the acquisition and general controls, you control whether the oscilloscope
is running or stopped. Other keys allow you to reset the oscilloscope to its
default setup, automatically configure the oscilloscope for the current input
signals (Autoscale), or erase the waveforms from the display.
Horizontal Controls
Using the horizontal controls, you configure the oscilloscope’s sweep speed
(seconds per division) and horizontal position of the waveform. You can also
view a magnified section of the waveform using the delayed sweep window,
which uses software to expand part of the acquisition memory.
Trigger Controls
Using the trigger controls, you set the conditions on which the oscilloscope will
tr ig ge r a nd ac qu ire a n i np ut sign al . Yo u c an se t u p a va ri et y o f t rigg er co nd iti on s.
Edge and glitch triggers can be selected from the front panel, and the
parameters for edge triggering can be set up here as well. Some glitch trigger
parameters (such as glitch width) and all advanced trigger configurations are
set up using the graphical interface.
Trigger configuration settings you make using the graphical interface are
reflected in the front-panel status indicators, and will remain set unless you
change them (either using the front panel or the graphical interface) or press
the Default Setup key. See “Using the Graphical Interface” on page 3-21 for
information on accessing the graphical interface.
Vertical Controls
Using the vertical controls, you set the vertical scaling (volts per division),
vertical offset, input impedance, and input coupling. You can also turn the
display on or off for a particular channel.
