Cursors
This method allows you to take measurements by moving the
cursors, which always appe ar in pairs, and reading their nume ric
values from the di splay readouts. There are two types of cursors:
Voltage and Time.
When you use cursors, be sure to set the Source to the waveform on
the display that you want to measure.
To use cursors, push the CURSOR button.
Voltage Cursors. Volta ge c ursors 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.
Automatic
The MEASURE Menu can take up to five automatic measurements.
When you take automatic measurements, the oscilloscope does all
the calculating for you. Because the measurements use the waveform
record points, they are more accurate than the graticule or cursor
measurements.
Automatic measurements use readouts to show measurement results.
These readouts are updated pe riodically as the oscilloscope acquires
new data.
For measurement descriptions, refer to page 94 in the Reference
chapter.
