IviScope Actual Record Length
IviScope Base Capability Group
This VI returns the actual number of points the oscilloscope acquires for each channel. After you configure the oscilloscope for an acquisition, call this VI to determine the size of the waveforms that the oscilloscope acquires. The value is greater than or equal to the minimum number of points you specify in the IviScope Configure Acquisition Record VI.
You must allocate a ViReal64 array of this size or greater to pass as the Waveform Array parameter of the IviScope Read Waveform and IviScope Fetch Waveform VIs.
 |
Note The oscilloscope may use records of different size depending on the acquisition type. You specify the acquisition type with the IviScope Configure Acquisition Type VI. |
 |
instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
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. |
 |
actual record length Returns the actual number of points the oscilloscope acquires for each channel. The driver returns the value of the IviScope Horizontal Record Length property. |
 |
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. |
