niScope Actual Record Length
Returns the actual number of points the digitizer acquires for each channel. After configuring the digitizer for an acquisition, call this VI to determine the size of the waveforms that the digitizer acquires. The value is equal to or greater than the minimum number of points specified in any of the Configure Horizontal VIs.
Use the record length returned by this VI as the input to the numSamples parameter of the Read and Fetch VIs.

instrument handle identifies a particular instrument session. | ||||||
 |
error in describes error conditions that occur before this VI runs. The default input of this cluster is no error. If an error already occurred, this VI returns the value of error in in error out. The VI runs normally only if no incoming error exists. Otherwise, the VI passes the error in value to error out. The error in cluster contains the following parameters:
| ||||||
 |
instrument handle out has the same value as the instrument handle. | ||||||
 |
actual record length returns the actual number of points the digitizer acquires for each channel.
NI-SCOPE returns the value held in the Horizontal Actual Record Length property; refer to Coercions of Horizontal Parameters for more information. |

 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
