8.4. Module Gain Adjustment
After setting the band properties, input RF signals into system. In CrossFire, the downlink input power of the
AU is specified as 0dBm and the maximum allowable input power is 15dBm. Therefore, estimate the signal
power before input RF signals. Monitor the downlink input power with a spectrum analyzer or check the
downlink input power in Combiner of the WebOMT in order to set attenuation for the downlink input power
within the appropriate range. The adjustable attenuation value of each AU Module is 30dB, which can be
set in Settings -> System Info -> Module X for each module or Settings -> Combiner -> Module X for
each port of module.See Figure 8-8 and Figure 8-9 for details.
