6.3.5.9 Viewing Historic Spectrum Management Metrics
Spectrum Management allows the system administrator to view the results of previous measurement
quantization periods. Holding down the shift key and clicking the appropriate channel on the local channel
spectrum plots activates this feature. This feature is available on both the master and slave webpage.
