This tutorial describes how to read binary files using the File Source block along side how to diagnose potential errors.

Please review the Writing Binary Files tutorial before continuing. A series of binary files were created with different formats that will be needed for this tutorial:

File Source Block

The File Source block reads from a binary file and then sends the samples to the output port. Drag the File Source block into a flowgraph. The block by default uses the complex data type (32-bit floats), represented by the blue output port:

Double clicking the File Source block brings up the properties and the ability to select different data types.
