Scope - Initiate Acquisition Step

Use the Scope - Initiate Acquisition step to initiate waveform acquisition for the specified Scope pins on all sites in the Pin Map context.

After this step is called, NI-SCOPE instruments connected to pins in the specified list leave the Idle state and wait for a trigger.
Note The Scope - Initiate Acquisition step must be used inside of an ECU Multi Test or ECU Action step with its module adapter configured as Sequence. The Scope - Initiate Acquisition step requires the Pin Map context passed from these steps as an input.

Use the Scope - Initiate Acquisition step edit tab in the TestStand Sequence Editor to specify the Pin Map context and the pins to query to obtain their associated NI-SCOPE instrument sessions.

Scope - Initiate Acquisition Step Settings Tab

The Scope - Initiate Acquisition Step Settings tab contains the following options:
  • Pin Map Context—Specifies a reference to a Pin Map Context object. This object describes a subset of pins, sites, and instruments from the pin map file and provides data pertinent to each site executing during a test.
  • Pins—Specifies the pins to query to obtain their associated NI-SCOPE instrument sessions. These instrument sessions are used to initiate waveform acquisition on the specified pins. The specified pins must be defined in the pin map file and included in the Pin Map context Pins and Relays list in the Options tab of the ECU Multi Test step.
    Note The Scope - Initiate Acquisition step filters the pins specified by instrument type ID. If none of the pins specified have an instrument type ID of niScope, the step will do nothing, as none of the specified pins are connected to NI-SCOPE instruments.
