Cursors
This method allows you to take measurements by moving the
cursors, which always appear in pairs, and reading their numeric
values from the display readouts. There are two types of cursors:
Voltage and Time.
When you use cursors, be sure to set the Source to the waveform that
you want to measure.
Voltage Cursors. Voltage cursors appear as horizontal lines on the
display and measure the vertical parameters.
Time Cursors. Time cursors appear as vertical lines on the display and
measure the horizontal parameters.
Automated
When you take automated measurements, the oscilloscope does all
the calculating for you. Because these measurements use the
waveform record points, they are more accurate than graticule or
cursor measurements.
Automated measurements use readouts to show measurement results.
These readouts are updated periodically as the oscilloscope acquires
new data.
Setting Up the Oscilloscope
You should become familiar with three functions that you will use
often when operating your oscilloscope: Autoset, saving a setup, and
recalling a setup. Included is a description of the default settings for
normal operation of the oscilloscope.
