Figure 67: Commissioning Procedure – MU Calibration Figure 68: Commissioning Procedure – MU Calibration Finish NOTE1: Calibration is to adjust MU and RU gain to assure that make sure system gain is 20dB, if the band have been calibrated, users can click to skip the process; if the band never been calibrated, users click in the step of MU Calibration and RU Calibration, software can still procede to the next step of MU and RU setup, but the system gain will be a little deviation with 20dB, so the final output power will be not same with the target DL output power. NOTE2: If there are more than one same band access to MU, then each access need to be calibrated in MU Calibration step, while in RU Cablibration step, users only need to calibrate the band one time, because all the same band shares the same PA. Step 5: Click to enter to RU Calibratiion page, refer to step 4 to finish RU calibration. NOTE1: Make sure the ANT port of RU is connected with dummy load or antennas before Calibration. Several RU can be calibrated simultaneously.

Note: ComFlex system reaches its rated output power (30dBm) when input power is +10dBm, if DL Input Power is over 10dBm, software will autoadjust the internal attenuator to make RU output power reach rated Power. (Input power range: 10-30dBm). Step 7: Click to enter to RU Setup page after finishing MU setup. Figure 73: Commissioning Procedure – RU Setup Click to set band related information of RU.
USER MANUAL FOR COMFLEX-4300 ENU STATUS : 1-0-0 Copyright - refer to title page Page 60 Figure 74: RU Frequency Band Table Two parameters need to be set in this step.  RF Switch: Set the RF switch status of Remote Unit.  Target DL Output Power: Expected DL output power setting. Note: Rated output power of ComFlex system is 30dBm, when Target DL Output Power is set less than 30dBm, software will auto adjust RU gain to make the RU output power reach the expected Power. Step 8: Click to enter to [Finish] page after finishing RU setup. Click to calibrate other bands. Click if all bands’ clibration is done. Figure 75: Commissioning Procedure – Finish Note: As the system calibration process is calibrated for single channel, so if there is more than one same band input, because of the power superposition, the band total output power will higer than target DL output power after the calibration is complete. The calibration work is mainly to set device to reach it’s theoretical gain, so when there are two or more same bands access into and they have the same input power level, each channel will reach it’s rated
USER MANUAL FOR COMFLEX-4300 ENU STATUS : 1-0-0 Copyright - refer to title page Page 61 power, so the total output power will be (input A+gain) + (inputB+gain)+…+(inputN+gain). For example, if there are two 1900MHz bands acess to MU, each has 10dBm input power, the total output power of RU 1900MHz will be 30dBm+30dBm=33dBm. For Multi-channel same band access, 800+850 (which share the same PA) access and 700 Uper C + LowerABC (also shared PA), they all will have power superposition. In this situation, users need to adjust system gain manually; otherwise, the output power will be higher than 32dBm which will trigger alarms (See Chapter 6 for details). Refer to the method below for the gain adjustment: Suppose a band with N independent inputs, each input signal power are all X dBm. Apparently, there exists the following relationship between input and output after finished auto communication on WEB GUI: X dBm + Gain = 30dBm, then the total output power for N channels access is X dBm + Gain + 10*Log(N) = 30 + 10*Log(N), so Users need to set 10*Log(N) RFU ATT on WEB GUI for each channel.
