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

Adjacent channel leakage ratio (ACLR)
Measurement method: Ratio of the filtered mean transmitted power to the filtered mean
power in an adjacent channel; both the transmitted and the adjacent channel powers are
measured with a filter that has a RRC response with roll-off a = 0.22 and a band width
equal to the chip rate
Input power level range: +5 to +28 dBm/3.84 MHz
Input frequency ranges: 698 to 1000 MHz, 1400 to 1500 MHz, 1700 to 2000 MHz,
and 2480 to 2580 MHz
Measurement level ranging: Auto
Measurement triggers: Auto, protocol, immediate, and external
Measurement interval: 1 timeslot
Measurement result: dBc relative to in-channel transmitted power
Measurement accuracy: < ±0.8 dB (typically < ±0.5 dB), including the effects of the residual
floor, for measurements at –33 dBc at ±5 MHz offsets and –43 dBc at ±10 MHz offsets, and
±10 °C from the calibration temperature
Residual ACLR floor: < –53 dBc for ±5 MHz offsets, < –63 dBc for ±10 MHz offsets
Temperature range: +20 to +55 °C
