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.

available are displayed.

color references, an online help screen has been provided see Figure 61. This screen is
accessible from both the master and slave web pages.
