IviScope Is Invalid Waveform Element
IviScope Base Capability Group
After the read and fetch waveform VIs execute, each element in the waveform array contains either a voltage or a value indicating that the oscilloscope could not sample a voltage. The driver uses an IEEE-defined NaN (Not a Number) value to mark as invalid each element in the waveform array for which the oscilloscope could not sample a voltage. This VI determines whether a value you pass from the waveform array is invalid.

instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
element value Pass one of the values from the waveform array returned by the read and fetch waveform VIs. The driver uses an IEEE-defined NaN (Not a Number) value to mark as invalid each element in the waveform array for which the oscilloscope could not sample a voltage. The driver determines whether the value you pass is invalid. |

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. |
 |
is invalid Returns whether the Element Value is a valid voltage or a value indicating that the oscilloscope could not sample a voltage.
Valid Return Values: TRUE (1)—The Element Value indicates that the oscilloscope could not sample the voltage. FALSE (0)—The Element Value is a valid voltage. |
 |
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. |
