Inputs/Outputs

datatype_icon

session in

The instrument handle that you obtain from Initialize External Calibration. The handle identifies a particular instrument session.

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

Default value: No error

datatype_icon

channels

The channel(s) from which to acquire data.

Channel String Syntax

This input parameter has the following syntax 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
  • A combination of channels from multiple instruments, such as PXI1Slot3/0,PXI1Slot3/2-3,PXI1Slot4/2-3
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.
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.

Standard Error Behavior

datatype_icon

coefficient info

An array of structures containing gain and offset coefficients for a given channel.

datatype_icon

offset

The offset factor of the given channel.

Use for scaling binary data with the following formula: voltage = binary data x gain factor + offset
datatype_icon

gain

The gain factor of the given channel.

Use for scaling binary data with the following formula: voltage = binary data × gain factor + offset.
datatype_icon

reserved1

A reserved value. Do not use.

datatype_icon

reserved2

A reserved value. Do not use.
