IviScope Configure Acquisition Record (G Dataflow)

Last Modified: October 24, 2017

Configures the most commonly configured properties of the oscilloscope acquisition subsystem. These properties are the time per record, minimum record length, and the acquisition start time.

error out

Error information.

The node produces this output 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.

error in

Error conditions that occur before this node runs.

Default: No error

datatype_icon

acquisition start time (0.0 s)

Specify the length of time from the trigger event to the first point in the waveform record. If this value is positive, the first point in the waveform record occurs after the trigger event. If this value is negative, the first point in the waveform record occurs before the trigger event. The driver uses this value to set the IviScope>>Acquisition>>Acquisition Start Time property. Units: seconds Default Value: 0.0 s

datatype_icon

min record length (100 samples)

Pass the minimum number of points you require in the waveform record for each channel. The driver sets the IviScope>>Acquisition>>Horizontal Minimum Number of Points property to this value and configures the record length that the oscilloscope uses for waveform acquisition. Call the IviScope Actual Record Length VI to obtain the actual record length. Default Value: 100 samples Notes: (1) The oscilloscope may use records of different size depending on the acquisition type. You specify the acquisition with the IviScope Configure Acquisition Type VI.

datatype_icon

time per record (1.0E-3 s)

Pass the time in seconds that corresponds to the record length. The driver sets the IviScope>>Acquisition>>Horizontal Time Per Record property to this value. Units: seconds Default Value: 1.0E-3 s

datatype_icon

instrument handle out

The instrument handle that you obtain from the IviScope Initialize or IviScope Initialize With Options node. The handle identifies a particular instrument session.
