Inner loop power
Measurement method: Inner loop power control in the uplink is the ability of the UE
transmitter to adjust its output power in accordance with one or more TPC commands
received in the downlink; the absolute and relative power is reported for each power step
Measurement range: –61 to +28 dBm/3.84 MHz
Input frequency ranges: 800 to 1000 MHz, 1700 to 1990 MHz
Measurement accuracy:
Absolute power: < ±1.0 dB, typically < ±0.5 dB
Relative power:
–– < ±0.1 dB for range ≤ 1.5 dB (–51 to +28 dBm/3.84 MHz)
< ±0.184 dB for range ≤ 1.5 dB (–61 to –51 dBm/3.84 MHz)
–– < ±0.15 dB for range ≤ 3 dB (–51 to +28 dBm/3.84 MHz)
–– < ±0.174 dB for range ≤ 3 dB (–61 to –51 dBm/3.84 MHz)
–– < ±0.3 dB for range ≤ 26 dB (–61 to +28 dBm/3.84 MHz)
Temperature range: +20 to +55 °C
Temperature drift: Typically < 0.1 dB per 10 °C temperature change for the absolute power
measurements; typically < 0.025, 0.02, and 0.05 dB over +20 to +55 °C temperature range
for relative power ranges of 1.5, 3, and 26 dB respectively
Concurrency capabilities: Inner loop power measurements cannot be made concurrently
with other measurements

Dynamic power analysis
Measurement method: Graphical display of a series of channel power measurement
for a user-defined number of steps and step lengths
Input level range: –61 to +28 dBm/3.84 MHz
Data capture range: Combination of number of steps and step length cannot
exceed 58.26 ms
Measurement bandwidth: Selectable RRC filter on or off
Measurement interval: Settable from 0.01 to 12 ms (must be less than or equal to
the step length)
