| 4 | 1 | JANVIER, Thibault | * Constellation of the received signal |
| 5 | 1 | JANVIER, Thibault | * Magnitude error |
| 6 | 1 | JANVIER, Thibault | * Phase error |
| 7 | 1 | JANVIER, Thibault | * Error Vector Magnitude |

| 9 | 1 | JANVIER, Thibault | The digital measurements are carried out on the “Digital” tab. Here, it is possible to configure the USRP and control all the parameters that need to be known to successfully display the constellation of the signal to be analysed. The below table sums up the parameters that have been entered as inputs according to the parameters of the signal to be analysed. |
