5.4.4.2 Using Uplink Pilot Tone Generator
Each RU in the remote node is equipped with an Uplink Pilot Tone Generator which will generate a CW RF
tone out of the RU back towards the FIU and BIU.. By measuring the RF power at the RXout port of the BIU
the end-to-end uplink system gain can be verified, and band-to-band / node-to-node, variations calibrated
without additional test equipment required at the Remote Node.
Verify the end-to-end Uplink Gain for each frequency band as follows:
1. Click on the RU for the desired frequency band. The component window ;will pop up as shown in
Figure 52 Up/Down Link Verification
a. Uplink Pilot Frequency: Set the frequency to the center of the spectrum to be used in the
system (if the operator licensed bands are not known set the frequency to center of the band
e.g. 1732.5 MHz for AWS band)
b. Uplink Pilot Frequency Switch: select ON from the drop-down box
c. Click Save to turn the Uplink Pilot generator ON
2. Connect an RF power meter to the corresponding RXout port of the BIU
a. A -6 dBm value in the Uplink Pilot Frequency Output Power field of the RU corresponds to an
equivalent signal of -60 dBm at the input to the RU
