Analyzing Captured Data - Agilent Technologies InfiniiVision 5000 Series Programmer's Manual

Getting Started
To collect data, you use the :DIGitize command. This command clears the
waveform buffers and starts the acquisition process. Acquisition continues
until acquisition memory is full, then stops. The acquired data is displayed
by the oscilloscope, and the captured data can be measured, stored in
trace memory in the oscilloscope, or transferred to the controller for
further analysis. Any additional commands sent while :DIGitize is working
are buffered until :DIGitize is complete.
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. Agilent 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.
