4. Measurement Uncertainty
Where relevant, the following test uncertainty levels have been estimated for tests performed on the EUT as specified in CISPR 16-4-2. This uncertainty represents an expanded uncertainty expressed at approximately the 95% confidence level using a coverage factor of k = 2. Radiated Disturbance
Measurement Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): Horizontal: 30MHz~300MHz: 5.04dB 300MHz~1GHz: 4.95dB 1GHz~40GHz: 6.40dB Vertical: 30MHz~300MHz: 5.24dB 300MHz~1GHz: 6.03dB 1GHz~40GHz: 6.40dB Output Power Measuring Uncertainty for a Level of Confidence of 95% (U=2Uc(y)): 1.13dB

Remark:

1. The analyzer plots shown in this section were all taken with a correction table loaded into the analyzer.

The correction table was used to account for the losses of the cables and attenuators used as part of the

system to connect the EUT to the analyzer at all frequencies of interest.

2. For radiated emission tests, every axis (X, Y, Z) was also verified. The test results shown in the following

sections represent the worst-case emissions.

Report No.: 2209RSU053-U3 5.2. Output Power Measurement 5.2.1. Test Limit In the bands allocated and assigned for broadcast television and in the 600 MHz service band: 50 mW EIRP. In the 600 MHz guard band and the 600 MHz duplex gap: 20 mW EIRP. 5.2.2. Test Procedure N/A 5.2.3. Test Setting Average power measurements were performed only when the EUT was transmitting at its maximum power control level using a broadband power meter with a pulse sensor. The power meter implemented triggering and gating capabilities which were set up such that power measurements were recorded only during the ON time of the transmitter. 5.2.4. Test Setup

Emissions shall be investigated up to the 10th harmonic of the fundamental. All the emissions shall be demonstrated using a QP detector below 1 GHz and a RMS Average detector above 1 GHz. All significant broadband and narrowband signals found in the preliminary sweeps were measured using a peak detector at a test distance of 3 meters. At each frequency at which a component is detected, the sample shall be rotated to obtain maximum response and the effective radiated power of that component determined by a substitution measurement.

Note 1: Measure Level (dBm) = Reading Level (dBm) + Substitution Factor (dB)

Note 2: For emission below 1GHz:

Substitution Factor (dB) = Cable Loss (dB) + Space Attenuation (dB) - Antenna Gain (dBi) - 2.15 (dB)

For emission above 1GHz:

Substitution Factor (dB) = Cable Loss (dB) + Space Attenuation (dB) - Antenna Gain (dBi) -

Pre_Amplifier Gain (dB)

Note 3: For emission below 1GHz:

QP measurement was not performed when peak level was lower than 6dB below the QP limit.
