Measure RIS Distribution Calibration (G Dataflow)

Version:
    Last Modified: March 3, 2017

    Takes an acquisition from a specified channel and retrieves the initial X value, which includes the time-to-digital conversion.

    This function performs the acquisition by calling Read Waveform 2,000 times. The time-digital conversion should be a uniform distribution between two sample points, because triggers should occur randomly. To test this distribution, the distribution of initial X values is created. The percentage of triggers in the smallest bin of this distribution is returned for comparison to a specification to determine if RIS is operating correctly.

    session in

    The instrument handle that you obtain from Start 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

    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

    max time

    The maximum time, in milliseconds, to allow for each acquisition.

    Default: 10000

    datatype_icon

    channels

    The channel to calibrate.

    Channel String Syntax

    This input parameter has 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.
    • All channels, which is designated by an empty string.

    Note  

    The order of channels in a list is important. The attributes are set on the channels in the order they occur in the string.

    datatype_icon

    distribution size

    The number of bins in the initial x distribution.

    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.

    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.
    datatype_icon

    min bin percent

    The percent of triggers in the minimum bin. Valid values are between 0 and 100.0

    datatype_icon

    distribution array

    The distribution of trigger times.
