Specifies the expected maximum amplitude of the input signal for frequency and period measurements.

Note This feature is supported on the NI 4080/4081/4082 and the NI 4070/4071/4072.

Inputs/Outputs

  • civrn.png instrument handle —

    instrument handle identifies a particular instrument session.

  • cerrcodeclst.png error in (no error) —

    error in (no error) describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

  • cdbl.png Frequency Voltage Range —

    Frequency Voltage Range sets the expected maximum amplitude of the input signal.

    Refer to the help section for your device for a list of valid values. NI-DMM sets the Frequency Voltage Range property to this value. The minimum peak-to-peak signal amplitude that can be detected is 10% of the specified Frequency Voltage Range.

    Auto Range ON (-1.0) Configures the DMM to take an Auto Range measurement to calculate the voltage range before each frequency or period measurement.
    Auto Range OFF (-2.0) Disables Auto Ranging. NI-DMM sets the voltage range to the last calculated voltage range.
  • iivrn.png instrument handle out —

    instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls.

  • ierrcodeclst.png error out —

    error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
