Sequencing Graphic
Displays the play list graph according to the current configuration.
The graph shows the segment sequence, the segment number and the number of
times, the segment is repeated; considered are only the active segments.
Remote command:
n.a.
New Sequencing List
Opens the "Select Sequencing List" dialog to enter the name of the new file.
Remote command:
n.a.
Load Sequencing List
Opens the "Select Sequencing List" dialog to select an existing play list file.
Remote command:
n.a.
Save Sequencing List
Saves the current entries of the table in a play list file.
The default file name of the play list file is the same as the multi segment waveform file
name, but it can be changed.
Play list files have the file extension
*.wvs
.
Remote command:

Typical Applications for Multi Segment Waveforms
This section gives examples of the typical applications for multi sgment waveforms.
High Speed Switchovers
To test DUTs/chips using different test signals at high throughput requires extremely
fast switchovers (for instance when testing ATE devices during manufacture). The fol-
lowing settings enable switching times of approx. 5 us and the test signals are scrolled
through with the aid of an external trigger signal:
1. "Trigger Mode" = "Auto"
2. "Trigger Source" = "External Trigger"
3. If the waveforms have different sample rates:
"Clock Mode" = "Highest" or "User" (when creating the waveform in the Multi Seg-
ment Editor)
Flexible Dynamic Switchovers
When testing DUTs using different test signals, it may be necessary to switch dynami-
cally and flexibly between any of the test signals, for instance depending on the out-
come of the previous test. When using remote control via an external computer, the fol-
