Configure Vertical (G Dataflow)

Version:
    Last Modified: March 3, 2017

    Configures the most commonly configured properties of the digitizer vertical subsystem, such as the range, offset, coupling, probe attenuation, and the channel name.

    Some features are not supported by all digitizers.

    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

    vertical range

    The absolute value of the input range for a channel.

    For example, to acquire a sine wave that spans between -5 and +5 V, set vertical range to 10.0 V.

    Default: 10

    datatype_icon

    vertical offset

    The location of the center of the range with respect to ground.

    For example, to acquire a sine wave that spans between 0.0 and 10.0 V, set this parameter to 5.0 V.

    Default: 0

    datatype_icon

    probe attenuation

    The probe attenuation for the input channel.

    Default: 1

    datatype_icon

    vertical coupling

    The method used to couple the input signal.

    When input coupling changes, the input stage takes a finite amount of time to settle.

    Name Value Description
    AC 0 Couples the input signal with an AC current.
    DC 1 Couples the input signal with a DC current.
    Ground 2 Couples the input signal with a ground signal.

    Default: DC

    datatype_icon

    channel enabled

    A Boolean value that specifies whether the channel is enabled for acquisition.

    True The channel is enabled for acquisition.
    False The channel is not enabled for acquisition.

    Default: True

    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.

    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.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported
