Cursors
This method allows youto take measurements by moving the
cursors, which always appear in pairs, and reading the ir 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 on
the display that you want to measure.
To use cursors, push the CURSOR button.
Voltage Cursors. Voltage cursors appear as horizonta l lines on the
display and measure the vertica l parameters.
Time Cursors. Time cursors appearas vertical lines on the display and
measure the horizontal paramete rs.
Automatic
The MEASURE Menucan take up to five automatic measurements.
When you take automatic measurements, the oscilloscopedoes all
the calculating for you. Because the measurem ents uset he waveform
record points, they are more accurate than the gra ticule or cursor
measurements.
Automatic measurements use readouts to show measurement results.
These readouts are updated periodically as the oscilloscope acquires
new data.
For measurement descriptions, refer to page 94 in the Reference
chapter.
