866884045632254
Test conditions:
Ambient Temperature:15℃-35℃
Relative Humidity:30%-60%
Air pressure: 86-106kPa
Test Results:
Pass

Item
Uncertainty
Expanded Uncertainty
0.52 dB (k=2)
Test Setup
During the test, the EUT was controlled via the Wireless Communications Test Set to ensure max
power transmission and proper modulation and measured by spectrum analyzer.
Test Method
The transmitter output was connected to a CMW500 through a coaxial RF cable and directional
coupler, and configured to operate at maximum power. The peak to average ratio was measured at
the required operating frequencies in each Band on the Spectrum Analyzer.
Note: Only worst case result is given below.
