Sequence Mode Setup - LeCroy WaveRunner Xi series Operator's Manual

AVE UNNER I
Each individual segment can be zoomed or used as input to math functions.
The instrument uses the sequence timebase setting to determine the capture duration of each segment: 10 x
time/div. Along with this setting, the oscilloscope uses the desired number of segments, maximum segment
length, and total available memory to determine the actual number of samples or segments, and time
However, the display of the complete waveform with all its segments may not entirely fill the screen.
You can also use S equence mode in remote operation to take full advantage of the instrument's high data-
transfer capability.

Sequence Mode Setup

Note: Once a single acquisition has started, you can interrupt the acquisition at any time by pressing the Single
front panel button a second time. In this case, the segments already acquired will be retained in memory.
1. In the menu bar, touch Timebase, then touch Horizontal Setup... in the drop-down menu.
2. Touch the Sequence mode button:
3. Touch the Sequence tab. Under Sequence Options, touch inside the Num Segments field and enter the
number of segments you want to display, using the pop-up
. Touch inside the Timeout field and enter a timeout value.

Note: The timeout period accounts for instances when a Num Segments miscount occurs for some reason
and the oscilloscope waits indefinitely for an unforthcoming segment. During that time, no oscilloscope
functions are accessible. By means of a timeout value, however, the acquisition will be completed, the
waveform displayed, and control of the oscilloscope returned to the user after the timeout has elapsed.
5. Touch the Enable Timeout checkbox.
6. In the menu bar, touch Display, then Display Setup... in the drop-down menu.
7. At the far right of the Display dialog, under "Sequence," touch inside the Display mode field, and make a
selection from the pop-up menu. Display modes are different ways to view your waveforms, as explained on
the next page.
8. Touch inside the Num seg displayed field and enter a value from 1 to 80, using the pop-up numeric keypad
9. Touch inside the Starting at field and enter a starting segment number, using the pop-up numeric keypad.
