Error Vector Magnitude (EVM) - PRACH (6.5.2.1) 3.1.21.
1. Execute TESTPRM IDLE_PRACHEVM1 to set Test Parameter to Idle - PRACH EVM (Test Point1).
2. Execute SWPANDPG when call processing is Idle (Regist) and SWP when processing is Connected to
measure Modulation Analysis (PRACH).
3. Execute EVM? AVG to read the EVM measurement result.
4. Execute EVMPASS? to check that the EVM Pass/Fail judgment is Pass.
5. Execute TESTPRM IDLE_PRACHEVM2 to set Test Parameter to Idle/Call - PRACH EVM (Test Point2).
6. Execute steps 2 to 4.
