With the ZBUC, FSK Monitor and control comes standard. This allows the Compact Outdoor 
SSPB to be fully and remotely monitored and controlled through the system’s IFL. An 
embedded controller enables remote communication and fault detection via the IF input 
between the SSPA and a Paradise Datacom Evolution Series L-Band modem. This signal 
consists of a 650 KHz Frequency Shift Keyed carrier that is multiplexed onto the L-Band input 
IFL along with the 10 MHz reference signal. The monitor and control functionality is explained 
in detail in Section 10. 
 
The FSK input has a center frequency of 650 KHz with a ±5% tolerance. The FSK deviation is 
±60 KHz, with +60 KHz being a “mark” and -60 KHz being a “space”. The FSK input will work 
over an input power range of -5 to -15 dBm. The FSK characteristics are summarized below: 
 

Frequency   

 

650 kHz ± 5% 

FSK Deviation 

 

± 60 kHz nominal (+60 kHz mark) 

Deviation Tolerance  

± 50 kHz minimum, ± 70 kHz maximum 

Locking Range 

 

± 32.5 kHz 

Input Level Range   

-5 to -15 dBm 

Start Tone Time  

 

10 ms minimum
