ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATION Figure 3-8. Host Fwd Att Pop-Up Screen 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 (78.1 dB for 800/900 MHz SMR, 78.5 for 800 MHz, and 77.7 dB for 1900 MHz) and then adding the composite input signal level. The result (see sample calculation) is the amount of attenuation required.
ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATION 7. Calculate the total composite signal power using the following formula: Ptot = Pc + 10Log N Where, Ptot is the total composite power in dBm Pc is the power per carrier in dBm as measured in step 6, and N is the total number of channels. 8. Record the result measured in step 5 or calculated in step 7. 9. Place the AC circuit breaker switch (at the RU power panel) in the open (OFF) position. 10.

ADCP-75-187 • Issue 3 • September 2006 • Section 3: OPERATION 2.6 Reference Procedure: Enter Host Reverse Attenuation The level of the RF signal that should be input to the EBTS will vary depending on the type of EBTS, the receive distribution, and the number of channels present. To interface with the EBTS, the reverse path signal level must be adjusted to provide the signal level required at the EBTS input port(s). The HU provides from –1 to +30 dB of gain in the reverse path.
