IviDigitizer Send Software Trigger [ST]
IviDigitizerSoftwareTrigger Capability Group
This VI sends a software-generated trigger to the instrument. It is only applicable for instruments using interfaces or protocols which support an explicit trigger function. For example, with GPIB this VI could send a group execute trigger to the instrument. Other implementations might send a *TRG command.
Since instruments interpret a software-generated trigger in a wide variety of ways, the precise response of the instrument to this trigger is not defined. Note that SCPI details a possible implementation.
This VI should not use resources which are potentially shared by other devices (for example, the VXI trigger lines). Use of such shared resources may have undesirable effects on other devices.
This VI should not check the instrument status. Typically, the end-user calls this VI only in a sequence of calls to other low-level driver VIs. The sequence performs one operation. The end-user uses the low-level VIs to optimize one or more aspects of interaction with the instrument. To check the instrument status, call the appropriate error query VI at the conclusion of the sequence.
The trigger source property must accept Software Trigger as a valid setting for this VI to work. If the trigger source is not set to Software Trigger, this VI does nothing and returns the error Trigger Not Software.

instrument handle The instrument handle that you obtain from the IviDigitizer Initialize VI or IviDigitizer Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviDigitizer Initialize VI or IviDigitizer Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
