Clears the waveform statistics on the channel and measurement you specify.

Clears the statistical information and the multi-acquisition array measurements. Every time a measurement is called, the statistics information is updated, including the min, max, mean, standard deviation, and number of updates.

session in

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

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

channels

The channel from which to acquire data.

Channel String Syntax

You can input channels with the following options:
  • A single channel, such as 0
  • A list of channels, such as 0,1 or 3,2,1,0.
  • A range of channels, such as 0-7 or 0:7.
spd-note-note
Note  

The order of channels in a list is important. The data for each channel is returned in the order the channels occur in the list.

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.
