IviScope Configure TV Trigger Line Number
IviScopeTVTrigger Capability Group [TV]
This VI configures the TV line upon which the oscilloscope triggers. The line number is absolute and not relative to the field of the TV signal.
 |
Note This VI affects instrument behavior only if the trigger type is set to IVISCOPE_VAL_TV_TRIGGER and the TV trigger event is set to IVISCOPE_VAL_TV_LINE_NUMBER. Call the IviScope Configure Trigger and the IviScope Configure TV Trigger Source [TV] VIs to set the trigger type and TV trigger event before calling this VI. |
 |
instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
line number Pass the line on which you want the oscilloscope to trigger. The driver sets the IviScope TV Trigger Line Number [TV] property to this value.
The line number is independent of the field. This means that to trigger on the first line of the second field, you must specify a line number of 263 (if we assume that field one has 262 lines). Default value: 1 |
 |
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 IviScope Initialize or the IviScope Initialize With Options VI. |
 |
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. |
