Table 3: DVB-S2 card characteristics (Option DS2 only)
1
Characteristic
Description
Input frequency range
950 MHz to 2150 MHz (center frequency) with 1 MHz step size
Input signal amplitude range, typical
–60 dBm to –30 dBm
Use high quality shielded cables and higher input level to prevent ingress of interfering
signals. This is particularly important at the tuned frequency where the input circuitry is
by design most sensitive.
Modulation format
DVB-S (ETSI EN 300 421) QPSK
DVB-S2 (ETSI EN 302 307) QPSK, 8PSK, 16APSK, and 32APSK including VCM, ACM,
multiple input streams (MIS) and Generic Stream (GS)
Symbol rate
2-40 MSps
FEC modes
S1 QPSK: 1/2, 2/3, 3/4, 5/6, 7/8
S2 QPSK: 1/4, 2/5, 1/2, 3/5, 2/3, 3/4, 4/5, 5/6, 8/9, 9/10
S2 8PSK: 3/5, 2/3, 3/4, 5/6, 8/9, 9/10
S2 16APSK: 2/3, 3/4, 4/5, 5/6, 8/9, 9/10
S2 32APSK: 3/4, 4/5, 5/6, 8/9, 9/10
Roll off
DVB-S: 35%
DVB-S2: 20%, 25%, 35%
Connector type
F type
Input termination impedance
75
Ω
nominal
Input return loss, typical
>10 dB @ 0 to 1 GHz
>4 dB @ 1 to 2 GHz
LNB power
Selectable; Off, 13 V, 14 V, 18 V, 19 V (DC)
LNB supply maximum current
150 mA
LNB 22 kHz signalling frequency
On or Off
LNB 22 kHz signalling amplitude
DiSEqC compliant (0.65 Vp-p typical)
Ultimate MER (Modulation Error Ratio),
with Equalizer
0 to 40 dB
