3.3.1.13. Carrier Leakage
3.3.1.13.1. MT8820C
[Measurements]
1. [PCC/SCC] Execute MOD_AVG 20 to set the average count of Modulation Analysis to 20 times.
2. [PCC/SCC] Execute TESTPRM TX_0DBM to set Test Parameter to TX1 – IBE/LEAK @ 0 dBm.
3. [PCC/SCC] Set UL RMC – Number of RB and Starting RB.
4. [PCC/SCC] Execute SWP to measure the Modulation Analysis.
5. [PCC/SCC] Execute CARRLEAK? MAX to read the Carrier Leakage measurement result.
6. [PCC/SCC] Execute CARRLEAKPASS? to check that the Carrier Leakage Pass/Fail judgment is Pass.
