Site Monitoring (Sensitivity Search) Option
The Sensitivity Search Tile is used to log the Sinad measurement of an injected signal over time.
Sensitivity Search is also used to log the spectrum trace of the RF signal. Sensitivity Search data
files are referred to throughout this section as Data Log Files.
Refer to Application Note 46891/951, Using the Aeroflex 3900 Series for Remote Site Monitoring, for
additional information on use of this option. A copy of this Application Note is included on the 3900

Accessing Site Monitoring
Sensitivity Search is selected from the Measurement drop-down menu on any of the minimized
Analog Duplex System Tiles. The Sensitivity Search Tile is only available when the Site
Monitoring option (390XOPT051) is installed in the Test Set.
Sensitivity Search Tile Layout
The main Sensitivity Search Tile contains parameters that must be defined to perform a Site
