ADCP-75-158 • Issue 1 • July 2003 • Section 2: Description The host forward path attenuator adjusts the level of the input RF signal to the HU. Using the forward path attenuator, an input signal with a nominal composite signal level of –9 dBm to –40 dBm can be adjusted to produce maximum power output. Additional external attenuation is required if the input signal level is greater than –9 dBm.
