Understanding Oscilloscope Functions
This chapter contains general information that you need to understand before
you use an oscilloscope. To use your oscilloscope effectively, you need to learn
about the following functions:
Setting up the oscilloscope
Triggering
Acquiring signals (waveforms)
Scaling and positioning waveforms
and their relationships to each other.
Setting Up the Oscilloscope
You should become familiar with several functions that you may use often when
operating your oscilloscope: Autoset, Autorange, saving a setup, and recalling
a setup.
Using Autoset
Each time you push the
Autoset
button, the Autoset function obtains a stable
waveform display for you. It automatically adjusts the vertical scale, horizontal
scale and trigger settings. Autoset also displays several automatic measurements
in the graticule area, depending on the signal type.
Using Autorange
Autorange is a continuous function that you can enable or disable. The function
adjusts setup values to track a signal when the signal exhibits large changes or
when you physically move the probe to a different point. To use autorange, push
the
Autoset
button for more than 1.5 seconds.
