Open Radio Access Network (O-RAN) has become crucial in today's world, where the need for communication is increasing day by day. A recently surfaced need for private networks caused by the diversed applications can be given as one of the examples. One of the most important initiatives, which has contributed to many fields from the industry just like Open RAN, is Open Air Interface (OAI). Today, open source codes of 5G technology are readily available in OAI platforms. In this way, it is possible to test the compliance of the newly developed methods with the standards or the existing cellular communication standards in the laboratory environment. In this study, data rate measurement is realized for different values of the modulation and coding scheme (MCS) in a test environment constituted by using 5G open source codes. Additionally, I/Q samples of the Physical Uplink Shared Channel (PUSCH) are observed. The real-time results obtained are compared with the theoretical analyzes found in the standards.
