Configure Acquisition (G Dataflow)

Last Modified: May 6, 2019

Configures how the digitizer acquires data and fills the waveform record.

datatype_icon

session in

Handle that identifies the NI-SCOPE instrument session as previously allocated by Initialize With Options.

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

acquisition type

The manner in which the oscilloscope acquires data and fills the waveform record.

Not all oscilloscopes support all acquisition types.

Name Value Description
Normal 0 Sets the oscilloscope to normal resolution mode. The oscilloscope can use real-time sampling or equivalent-time sampling.
Flex Res 1 Sets legacy oscilloscopes to flexible resolution mode, if supported.
DDC 3 Sets legacy oscilloscopes to DDC mode, if supported.
spd-note-note
Note  

To use DDC mode for the PXI/PCI-5142 or PXIe-5622, set this parameter to Normal and set the DDC Enabled property to True.

Default: Normal

datatype_icon

session out

Reference to the NI-SCOPE instrument session to pass to the next node in the program.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
