Extended range dynamic power measurement
Measurement method: Allows measurement of a UE’s transmitter output power across its
entire dynamic power (up to 90 dB) in one measurement cycle. This measurement requires
the UE be put into a test mode which forces it to transmit up to two power sequences and
analyzes the resulting UE output power using the test set

Measurement bandwidth: Selectable RRC filter on or off
Measurement range: –61 dBm to +28 dBm/3.84 MHz
Measurement accuracy:
–– ±1.0 dB (typically ±0.5 dB), at top 25 dB of dynamic range
–– ±1.0 dB (typically ±0.55 dB), at top 30 dB of dynamic range
–– ±1.0 dB (typically ±0.55 dB), at top 35 dB of dynamic range with RRC filter on
Measurement trigger: RF rise, external
Temperature range: +20 to +55°C
Temperature drift: Typically < 0.1 dB per 10 °C temperature change
