PD60 DVB S2 IF Satellite Modem
The Paradise QUANTUM Series PD60 Modem brings the bandwidth saving and robustness benefits of DVB-S2 to traditional SCPC services such as IBS and Drop & Insert.
Paired Carrier technology overlays transmit and receive carriers reducing satellite bandwidth by up to 50%. Paired CarrierTM technology is patented by Viasat Inc.
QUANTUM modems are fully backward compatible with Paradise Evolution modems when DVB-S2 and Paired Carrier are disabled.
SCPC Features, DVB-S2 Space Segment
Modes of operation:
- DVB-S2 outbound with SCPC return, or SCPC outbound with DVB-S2 return.
- DVB-S2 outbound and return.
- SCPC outbound and return.
- SmartLink mode where Tx/Rx SCPC features are combined with DVB-S2 space segment savings. All traditional SCPC features are supported including IBS, IDR, ESC, Drop & Insert, AUPC, etc.
- Data rate options to 60Mbps, 37.5Msymbol/s maximum.
- All the standard features and options of the Evolution Series Modem including IBS, IDR, Drop & Insert, etc.
- DVB-S2 FEC and modulation support.
- Paired Carrier ready. Requires just an upgrade.
- Ethernet plus a further 3 x traffic interfaces supporting a wide range of terrestrial interfaces.
- Supports up to two Quad E1 cards allowing up to 8 x E1s to be multiplexed onto a single carrier
- Available in IF, L-band, and IF plus L-band.
Web User Interface
A unique Web User Interface provides full Monitor & Control plus graphing of Eb/No, BER, Receive Power and other operating parameters, plus a Receive Spectrum Analyser, Receive Constellation Monitor and BER Tester for detailed signal analysis and performance validation via Internet Explorer. Logged graph data can be sent via email to any email address.
Simple to use EZ-BERT BER Tester Option allows real time bit error measurements through traffic or ESC channel, or between the terrestrial ports.

Built-in Receive Constellation Display
Paired Carrier Operation
Paired Carrier technology allows both the uplink and downlink signals to occupy the same space segment. An adaptive self-interference cancellation technique removes the uplink signal components generated by the local terminal from the received signal off satellite, allowing demodulation of the far end signal.
