Applies offset, in seconds, to the sample clock relative to the reference clock when using the onboard clock.

Each time this VI is called, the sample clock is offset from the reference clock by the specified amount of time.

Adjustment range: +-1 Sample Clock Period per call

Inputs/Outputs

  • civrn.png instrument handle —

    instrument handle identifies a particular instrument session.

  • cdbl.png delay —

    delay is the amount of time (in seconds) to delay the sample clock. This value is relative, so repeated calls to this VI delay the sample clock by this amount every time.

    Default Value: None

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • iivrn.png instrument handle out —

    instrument handle out has the same value as the instrument handle.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.

    Programming Patterns

    Use this VI when performing manual adjustment to correct for skew and jitter between oscilloscopes synchronized with NI-TClk.

    1. Apply time offset with this VI to reduce skew and/or jitter.
    2. Use the Oscillator Phase DAC Value property to convert this time offset into a value that can apply the manual adjustment across sessions and improve synchronization repeatability.

    For details on performing manual adjustment, refer to Improving NI-TClk Synchronization of Oscilloscopes with Manual Adjustment.
