Transferring the logic analyzer acquired data
This program uses the SYSTem:DATA query to transfer acquired data to
your controller. It is useful for getting acquired data for setting up the logic
analyzer by the controller at a later time. This query differs from the
SYSTem:SETup query because it transfers only the acquired data.
This program also uses the SYSTem:DATA command to transfer the logic
analyzer data from the controller back to the logic analyzer and load the
analyzer with the acquired data. The SYSTem:DATA command differs from
the SYSTem:SETup command because it transfers both the configuration
and the acquired data.
You should always precede the SYSTem:DATA query and command with the
SYSTem:SETup query and command if the acquired data depends on a specific
configuration. If you are only interested in the acquired data for post
processing in the controller and the data is not dependent on the configuration,
you can use the SYSTem:DATA query and command alone.
