SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS
EL970 IP Satellite Demodulator
Input interface
Dual L-band input (default)
• Connector 2 x F-type (F), 75 ohms;
• Return loss > 7 dB;
• Level -65/-25dBm;
• Frequency 950 - 2150 MHz;
• Adjacent signal < (Co+7) dBm/Hz where Co = signal level density.
IF-band input (optional, replaces one L-band input)
• Connector BNC (F) - 75 ohms;
• Return loss > 15 dB;
• Level -55 to -15 dBm;
• Frequency 50 - 180 MHz;
• Adjacent signal < (Co+7) dBm/Hz where Co = signal level density.
LNB power and control
• max. current 350 mA (on selected IFL input);
• voltage
- 11,5 -14 V (Vertical polarization);
- 16 -19 V (Horizontal polarization) & additional 22kHz +/- 4KHz (band
selection according to universal LNB for Astra satellites & DiSEqC
command transmission);
• 10 MHz reference.
