EVM measurement accuracy:
–– < 2.8% rms (typically < 2.4% rms) for UE EVM ≥ 1% rms, ≤ 2200 MHz
–– < 3.2% rms (typically < 2.8% rms) for UE EVM ≥ 1% rms, 2300 to 2580 MHz
Measurement triggers: Auto, protocol, immediate, external, and HS-DPCCH
HS-DPCCH trigger alignment: Adjustable over
–– Subframes: 0 to 5
–– Timeslots: Ack, Nack or CQI
–– Subslots: 0 to 0.5 timeslots
Other reported parameters with EVM:

IQ tuning
All measurements found in the waveform quality measurement are also available in the IQ
tuning measurement; the specifications are the same in both measurements.
