 ==== Analyze the results ====
-* Since we run Client and Base Stations in separate terminals, a minor modification in {{{hdf5_lib.py}}} is needed to specify the binary reference in the post-processing script: replace line 916 {{{tx_file_names = metadata['TX_FD_DATA_FILENAMES'].astype(str)}}} with {{{manual_file = ['ul_data_f_16QAM_52_64_10_1_1_A_0.bin']; manual_file = np.array(manual_file); tx_file_names = manual_file}}}

 * Once the hdf5 file is recorded (in this case, {{{logs/trace-uplink-2022-7-8-7-43-59_1_8x1_0_7.hdf5}}}), follow the **Analyze the HDF5 dataset** step [https://docs.renew-wireless.org/dev-suite/design-flows/cpp/sounder/ here] to analyze the results. For example, we can show the pilot and uplink IQ waveforms, Uplink User Constealltion along with its Error Vector Magnitude(EVM) and Symbol Error Rate(SER) values (in this case: EVM is 0.93%; SER is 5.63%]):

 where {{{--ref-frame=250}}} represents the reference frame to look at, and {{{--signal-offset=1775}}} represents the signal offset where this value might be different under different senerios.
