New Sequencing List
Opens the "Select Sequencing List" dialog to enter the name of the new file.
SCPI command:
n.a.
Load Sequencing List
Opens the "Select Sequencing List" dialog to select an existing play list file.
SCPI 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
.

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 following
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 Segment
Editor)
Flexible Dynamic Switchovers
When testing DUTs using different test signals, it may be necessary to switch dynamically
and flexibly between any of the test signals, for instance depending on the outcome of
the previous test. When using remote control via an external computer, the following
settings enable switching times of approx. 20 ms for segments with the same sample rate
and approx. 200 ms for segments with different sample rates:
1. "Extended Trigger Mode" = "Next Segment"
2. "Trigger Mode" = "Auto"
3. "Trigger Source" = "Internal"
