Performing spectrum clearance
After you have started up the RRH successfully, meaning that you have at least one enabled carrier with
uplink and downlink frequency information, you can move to Spectrum Clearance to identify any interfering
signals in the uplink carrier by performing the following measurements while keeping your CellAdvisor to
work as a BBU.
This instrument provides the following measurements in the BBU Emulation mode:
◼
Spectrum
◼
Spectrogram
◼
RSSI
◼
Dual spectrum
◼
Dual spectrogram
NOTE
It is very important that you maintain the Term mode cable connection as illustrated in
Figure 420 and keep the RRH connection on as you have done in the RRH configuration
verification.
Conducting spectrum measurement
In this Spectrum mode, you only need to change the following settings as needed.
