Spectrum Analyzer Page
The spectrum analyzer feature provides a useful pre-planning and troubleshooting tool. Perform a
spectrum analysis after deployment and just before commissioning to maintain a record of the
spectrum at the time of deployment. Figure 41 shows the Spectrum Analyzer page. Note that both
polarizations are independently measured when a scan is performed. Generally, a clear spectrum is
required for both polarizations for the radio to run in dual-polarization mode.

While a professional spectrum analyzer provides higher levels of control and precision for pre-
planning, the Spectrum Analyzer page allows evaluation of the RF spectrum as seen at the radio’s RF
input port prior to deployment. This is useful for pre-planning the center frequency and occupied
bandwidth, and to determine polarization and antenna type and mounting locations.
For troubleshooting, enable the spectrum analyzer to scan the desired segment or full band of the
frequency range. Select the step size and set the remote radio transmitter ON or OFF. This allows
viewing of the
clean
spectrum without the remote transmitter on and a comparison of the remote
transmitter in the midst of other signals.
