3.1 Uncertainty of Test
Parameters | Uncertainty |
---|---|
RF power, conducted | ±0.90 dB |
All emissions, radiated | ±5.36 dB |
Unwanted Emissions, conducted | ±0.90 dB |
Voltage (DC) | ±3.6 % |
Temperature | ±0.82°C |
Humidity | ±4.1% |
The following measurement uncertainty levels have been estimated for tests performed on the EUT as specified in TR 100 028-1, and TR 100 028-2. This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k=2.
4. Test Configuration
