NI-RFSA Named Trigger Types

Named trigger types in NI-RFSA define the action you want an instrument to take upon detecting a specific signal condition.

  • Start—Transitions an instrument into a state where the instrument can respond to Sample Clocks. This trigger transitions the instrument from a nonsampling state into a sampling state—the instrument starts sampling and storing data.

    Supported signal conditions: None, Digital Edge, Software

  • Reference—Establishes the reference point that separates pretrigger and posttrigger samples; transitions an instrument from the Wait for Reference Trigger sampling state into the Post Reference Trigger sampling state. In the Post Reference Trigger sampling state, a counter begins counting Sample Clock cycles. When the configured number of samples is acquired, the device transitions into a Done state.

    Supported signal conditions: None, Digital Edge, IQ Power Edge, Software

  • Advance—Initiates the acquisition of the additional records in a multirecord acquisition.

    Supported signal conditions: None, Digital Edge, Software
