Press the
Run Test
softkey to run the selected signal quality test.
When tests are run, the oscilloscope stops acquisitions if they are
running, analyzes the data on screen, and then displays the results.
When the test completes, the results are automatically displayed. You
can press the
Display Results
softkey to disable or reenable the test
results display.
The analyzed acquisition remains on screen and can be viewed by
moving or dismissing the results dialog box.
You can run tests when the oscilloscope is already stopped. This is
useful in the case of embedded hosts (and other cases) where the
device under test (DUT) may not easily be placed in a test mode, and
you want to analyze already acquired data.
