EVM equalizer spectrum flatness (6.5.2.4) 3.1.26.
This chapter describes a UL measurement example where (Modulation, RB) is (QPSK, FullRB).
1. Execute MOD_AVG 20 to set the average count of Modulation Analysis to 20 times.
2. Execute TESTPRM TX_MAXPWR_Q_F to set Test Parameter to TX1 - Max. Power (QPSK/FullRB).
3. Execute SWP to measure Modulation Analysis.
4. Execute SPECFLAT_RP1? MAX to read the MAX Spectrum Flatness (Spectrum Flatness ≥ 3 MHz (PR1))
measurement result.
5. Execute SPECFLAT_RP2? MAX to read the MAX Spectrum Flatness (Spectrum Flatness < 3 MHz (PR2))
measurement result.
6. Execute SPECFLAT_RP12? MAX to read the MAX Spectrum Flatness (Spectrum Flatness RP12) measurement
result.
7. Execute SPECFLAT_RP21? MAX to read the MAX Spectrum Flatness (Spectrum Flatness RP21) measurement
result.
8. Execute SPECFLATPASS? to check that the Spectrum Flatness Pass/Fail judgment is Pass.
