You could also put the oscilloscope into run mode, then use a wait loop in your
program to ensure that the oscilloscope has completed at least one acquisition
before you make a measurement. Keysight does not recommend this because the
needed length of the wait loop may vary, causing your program to fail. :DIGitize, on
the other hand, ensures that data capture is complete. Also, :DIGitize, when
complete, stops the acquisition process so that all measurements are on displayed
data, not on a constantly changing data set.
Analyzing Captured Data
After the oscilloscope has completed an acquisition, you can find out more about
the data, either by using the oscilloscope measurements or by transferring the
data to the controller for manipulation by your program. Built-in measurements
include: frequency, duty cycle, period, positive pulse width, and negative pulse
width.
Using the :WAVeform commands, you can transfer the data to your controller. You
may want to display the data, compare it to a known good measurement, or simply
check logic patterns at various time intervals in the acquisition.
