4.4 FSK Monitor and Control
FSK Monitor and control comes standard with the converter. This allows the Mini 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 Teledyne 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 external reference signal. The monitor and control functionali-
ty is explained in detail in
Section 9
.
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
