You will notice a Carrier Monitoring Toolbar added to the left of the display.  More on 
this later. 

 

We could connect another RF feed to other switch port(s) on the Decimator and bring 
in other carriers from different feeds, but for this example, all 4 carriers will be on 
Switch Port 1.  If you need to change the switch port, click the SYSTEM button and set 
the Switch Port to 2. 

 

We will go ahead and repeat the above bulleted steps for the other 3 carriers with the 
adjustments in settings specified in Table 1 to create a total of 4 measurements.  
Configure these settings using the FREQUENCY and SPAN  buttons as before or lock 
them in using the Overview Bar.  Your choice.
