Configure Channel Characteristics (G Dataflow)

Version:
    Last Modified: March 3, 2017

    Configures the properties that control the electrical characteristics of the channel.

    This function configures the input impedance and the bandwidth.

    datatype_icon

    session in

    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

    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.

    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

    input impedance

    The input impedance for the channel.

    Name Value Description
    1 mega ohm 0 Sets the input impedance to 1 mega ohm.
    50 ohms 2 Sets the input impedance to 50 ohms.

    Default: 1 mega ohm

    datatype_icon

    maximum input frequency

    The bandwidth of the channel at which the input circuitry attenuates the signal by 3 dB.

    Pass 0 for this value to use the hardware default bandwidth. Pass -1 for this value to achieve full bandwidth.

    Default: 0.00

    datatype_icon

    session out

    Passes the instrument handle to the next node in the program. This parameter has the same value as session in.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.
