Error Vector Magnitude (EVM) - PUSCH (6.5.2.1) 3.1.19.
This chapter describes UL measurement examples where (Modulation, RB) is (QPSK, PartialRB), (QPSK, FullRB),
(16QAM, PartialRB) or (16QAM, FullRB).
1. Execute MOD_AVG 20 to set the average count of Modulation Analysis to 20 times.
[(QPSK, PartialRB) measurements]
2. Execute TESTPRM TX_MAXPWR_Q_P to set Test Parameter to TX1 - Max. Power (QPSK/PartialRB).
3. Execute ULRB_POS MIN to set UL RB Position to Min (#0).
4. Execute SWP to measure Modulation Analysis.
5. Execute EVM? AVG to read the EVM measurement result.
6. Execute EVMPASS? to check that the EVM Pass/Fail judgment is Pass.
7. Execute RSEVM? AVG to read the Reference Signal EVM measurement result.
8. Execute RSEVMPASS? to check that the Reference Signal EVM Pass/Fail judgment is Pass.
9. Execute ULRB_POS MAX to set UL RB Position to Max (#max).
10. Execute steps 4 to 8.
11. Execute TESTPRM TX_M40DBM_Q_P to set Test Parameter to TX1 - EVM/IBE/LEAK @ -40 dBm
(QPSK/PartialRB)
12. Execute steps 3 to 10.
[(QPSK, FullRB) measurements]
13. Execute TESTPRM TX_MAXPWR_Q_F to set Test Parameter to TX1 - Max. Power (QPSK/FullRB).
14. Execute steps 4 to 8.
15. Execute TESTPRM TX_M40DBM_Q_F to set Test Parameter to TX1 - EVM @ -40 dBm (QPSK/Full RB).
16. Execute steps 4 to 8.
[(16QAM, PartialRB) measurements]
17. Execute TESTPRM TX_MAXPWR_16_P to set Test Parameter to TX1 - Max. Power (16QAM/PartialRB).
18. Execute steps 3 to 10.
19. Execute TESTPRM TX_M40DBM_16_P to set Test Parameter to TX1 - EVM @ -40 dBm (16QAM/Partial RB).
20. Execute steps 3 to 10.
[(16QAM, FullRB) measurements]
21. Execute TESTPRM TX_MAXPWR_16_F to set Test Parameter to TX1 - Max. Power (16QAM/FullRB).
22. Execute steps 4 to 8.
23. Execute TESTPRM TX_M40DBM_16_F to set Test Parameter to TX1 - EVM @ -40 dBm (16QAM/Full RB).
24. Execute steps 4 to 8.
NOTE 1: The UL RB Position for PartialRB allocation is Min (#0) or Max (#max).
