H.2 Received Total Wideband Power

H.2.1 Absolute RTWP measurement

1. Terminate the BS RX inputs, measure the RTWP and record it.

2. Attach a signal generator to the RX input connector and increase the power until the BS reported RTWP value (Irep) has increased 3 dB.

3. Measure the signal power level delivered from the signal generator. This signal level is now called the "Internally generated noise" (Ni).

4. Sweep the signal generator power such that the sum of internally generated noise (Ni) and signal generator power (I) is swept through the defined conditions range.

5. Check that: |(Ni+I)-Irep| meets the accuracy requirements specified in chapter 9.2.1.1

Note that Iob= (Ni+I)

H.2.2 Relative RTWP measurement

1. Terminate the BS RX inputs, measure the RTWP and record it.

2. Attach a signal generator to the RX input connector and increase the power until the BS reported RTWP value (Irep) has increased 3 dB.

3. Measure the signal power level delivered from the signal generator. This signal level is now called the "Internally generated noise" (Ni).

4. Sweep the signal generator power such that the sum of internally generated noise (Ni) and signal generator power (I) is swept through the defined conditions range.

5. The difference between the reported RTWP values shall meet the accuracy requirements specified in chapter 9.2.1.2.

Note that Iob= (Ni+I)
