Paradise RA 5785 manual FSK Monitor and Control

Notes:

1)The external reference option requires the system operator to provide system reference to the BUC/SSPB. The system will not lock and will have no output without external reference applied.

2)Internal reference option allows for either internal or external reference operation.

The 10 MHz crystal reference used in the internal reference of the converter has the following specifications:

Frequency Stability:	≤±1 • 10-8over the temperature range -40 to +90 °C
	≤±1 • 10-9aging per day
	≤±5 • 10-8aging per year
Warm up time:	20 minutes for better than ≤±1 • 10-8
Phase Noise:	10 Hz	-120 dBc/Hz
	100 Hz	-140 dBc/Hz
	1 KHz	-145 dBc/Hz
	10 KHz	-152 dBc/Hz
	100 KHz	-155 dBc/Hz
Frequency Accuracy:	Factory preset to ±1 • 10-8

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 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 functionality is explained in detail in Section 8.

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
