Initiates an acquisition, waits for it to complete, and performs the specified waveform measurement for multiple channels and records.

Use niScope Read Measurement for a single channel and record.

Inputs/Outputs

  • cdbl.png timeout —

    timeout is the time (in seconds) to wait for the data to be acquired. Use 0 for this parameter to tell NI-SCOPE to fetch whatever is currently available. Using -1 for this parameter implies infinite timeout.

  • civrn.png instrument handle —

    instrument handle identifies a particular instrument session.

  • cstr.png channels —

    channels specifies the channel(s) from which to acquire data. For more information, refer to Channel String Syntax.

  • ci32.png scalar measurement —

    scalar measurement is the measurement to perform on the waveform read from the digitizer.

    Refer to the list of NI-SCOPE Scalar Measurements for more information.

  • 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.

  • i1ddbl.png results —

    results contains the measurements acquired as a one-dimensional array; if you specify a channel list, NI-SCOPE returns the waveforms in the list order. NI-SCOPE returns these records sequentially, so all record 0 waveforms are first.

    For example, with a two-channel list, you would have the following index values:

    index 0 = record 0, channel 0

    index 1 = record 0, channel 1

    index 2 = record 1, channel 0

    index 3 = record 1, channel 1

  • ierrcodeclst.png error out —

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