DVB-S/S2 Modulator-v.2.1

DVB-S/S2 Modulator v.2.1 is a next-generation satellite RF modulator engineered for modern DVB broadcasting environments. Supporting modulation formats up to 32APSK and symbol rates reaching 45 Msym/s, it delivers exceptional bandwidth efficiency, making it ideal for high-density satellite uplinks, MVDS systems, RF distribution platforms and digital TV headend deployments.

Featuring ASI input, L-band output (950–2150 MHz), ultra-high RF output power up to 115 dBµV and MER above 27 dB, the modulator provides reliable signal purity for professional DVB-S/S2 services. Ethernet-based VCC software enables full remote configuration and monitoring, while optional 10 MHz reference and DC injection support advanced system integration with BUCs and RF chains.

✅ High-performance DVB-S/S2 modulation with 32APSK support

The modulator supports QPSK, 8PSK, 16APSK and 32APSK, enabling significantly higher spectral efficiency for modern DVB-S2 networks. With flexible FEC options and pilot control, operators can optimize performance under various RF conditions. This makes the device ideal for high-bitrate multiplexes, transport streams and backbone broadcast infrastructure.

✅ Extended symbol-rate range up to 45 Msym/s

A maximum symbol rate of 45 Msym/s ensures compatibility with wideband satellite carriers and MVDS infrastructure. Even when operating at high symbol rates, the device maintains excellent signal stability and MER figures. This flexibility allows operators to maximize throughput depending on spectrum availability.

✅ Professional L-band output with up to 115 dBµV RF level

One of the strongest RF outputs in its class, the modulator delivers up to 115 dBµV, ensuring compatibility with long RF paths, passive splitters and headend combiners. Adjustable attenuation lets operators fine-tune RF power for precise system balancing and interference mitigation.

✅ Scalable from 1 to 32 channels for dense DVB headends

The DVB-S/S2 Modulator v.2.1 can be manufactured with 1 to 32 independent RF channels, allowing operators to build compact multi-carrier DVB-S2 platforms. This dramatically reduces rack space and simplifies multi-carrier uplink configurations compared to traditional single-channel modulators.

📌 Key features

• Support for QPSK, 8PSK, 16APSK and 32APSK modulation

The modulator supports all DVB-S/S2 constellation schemes up to 32APSK, enabling advanced high-capacity satellite carriers. This provides exceptional flexibility for operators who need to scale bandwidth based on service load. Compatibility with LDPC FEC ensures strong signal robustness.

• Symbol rates up to 45 Msym/s with fine adjustment

With support for symbol rate tuning from 1 to 45 Msym/s (depending on modulation type), operators can precisely adapt the carrier bandwidth. Fine 1 KSymb/s adjustment steps allow precise matching to channel plans and regulatory spectrum masks. This ensures optimal performance across diverse RF environments.

• High MER output (>27 dB) for clean and stable carriers

High MER ensures superior constellation quality and receiver demodulation stability. The device maintains professional RF purity across all modulation formats, even at high output levels. This is essential for long-distance RF feeds, satellite uplinks and multi-transmitter MVDS deployments.

• RF output level up to 115 dBµV

A powerful RF output makes the modulator suitable for headend installations with long cable runs and complex splitting networks. Adjustable attenuation ensures the output can be precisely aligned with system requirements. This eliminates the need for external amplifiers in many configurations.

• Optional 10 MHz reference and DC power injection

The modulator can provide 10 MHz reference synchronization and 24V/3A DC power injection for BUCs. This dramatically simplifies system wiring by eliminating external reference generators and power injectors. It is particularly useful for compact satellite uplinks and relay stations.

⚙️ Main functions

• Ethernet remote management via VCC software

Full remote configuration enables operators to manage modulation parameters, RF output power, symbol rate and FEC settings from anywhere. The intuitive interface improves operational efficiency in distributed and unmanned broadcast sites. Real-time monitoring ensures complete visibility into system health.

• Non-volatile memory for automatic recovery after power loss

All configuration data is stored internally, allowing the device to restore operation immediately after power is restored. This guarantees uninterrupted broadcasting in mission-critical DVB environments. Operators do not need to reconfigure the device manually after outages.

• Built-in electrical protection systems

Integrated over-voltage, overload and short-circuit protection safeguard the RF chain and power circuits. This is crucial for 24/7 broadcast operations where equipment must be resistant to environmental and electrical fluctuations. Reliability is ensured even under heavy loads.

• Wide compatibility with professional broadcast infrastructure

With ASI input support, adjustable symbol rates, multiple modulation formats and scalable channel count, the modulator fits into any DVB-S/S2 headend. This makes it ideal for TV operators, MVDS providers, satellite broadcasters and digital transport networks.

🧩 Applications

• Satellite broadcasting and DVB-S/S2 uplink platforms

The modulator supports all modern DVB-S2 features needed for high-capacity uplinks, including 16APSK/32APSK, adjustable FEC and pilots. Broadcasters can create efficient carriers for satellite distribution, backbone networks and contribution feeds.

• MVDS and microwave broadband distribution systems

High MER and powerful RF output make the device suitable for MVDS clusters serving large geographical areas. Operators can feed multiple microwave transmitters from a single headend modulator with consistent performance across channels.

• Digital TV headends and professional RF multiplexing

The DVB-S/S2 Modulator v.2.1 integrates seamlessly with encoders, multiplexers, scramblers and IPTV gateways. It enables flexible output strategies, whether carriers feed satellite uplinks, RF combiners or terrestrial retransmission systems.

• Broadcast laboratories, R&D and receiver testing

Thanks to precise symbol-rate control, modulation flexibility and strong RF output, the modulator is ideal for testing demodulators, receivers and antenna systems. It is widely used in engineering labs and certification environments.
