IviCounter Initiate VI
IviCounterBase Capability Group
This VI initiates a measurement based on the preset configuration. You must configure the measurement type and input channel before calling this VI. After you call this VI, the Counter leaves the Idle state and waits for a trigger. The counter makes a measurement for each channel you enable with the IviCounter Configure Channel VI. You must call the IviCounter Fetch VI in order to retrieve the result of the measurement.
 |
Note This VI does not check the instrument status. Typically, you call this VI only in a sequence of calls to other low-level driver VIs. The sequence performs one operation. You use the low-level VIs to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviCounter Error Query VI at the conclusion of the sequence. |
|
instrument handle The instrument handle that you obtain from the IviCounter Initialize VI or IviCounter 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 IviCounter Initialize VI or IviCounter 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. |
