3. Obtain the value of the total composite input signal level as determined in step 11 of
Section 2.3.
4. Determine the appropriate value to enter for the Host forward path attenuator by
subtracting the required system output level (per system design plan) from the system gain
(85 dB) and then adding the composite input signal level. The result (see sample
calculation) is the amount of attenuation required.
Atten = (System Gain) – (Required System Output Power) + (Composite Input Power)
5. Enter the attenuation value and click OK to close the pop-up screen and to make the
changes take effect.
