Request for a quote

The SR8 PROX is a cutting-edge professional demodulator supporting DVBS-2X. It handles a wide range of symbol rates, from 100 Ksps to 500 Msps in wideband mode.

It supports ACM and modulations up to 64 APSK, with optional support for 256 APSK.

Powered by the latest STMicroelectronics Oxford chipset, the SR8 PROX features an advanced HPP engine that delivers data rates up to 600 Mbps. It also includes an integrated Gigabit Ethernet switch for easy network integration. Like all AYECKA X-series products, it comes with a high-power processor and advanced web server management.

The device offers separate traffic and management interfaces to enhance cybersecurity and multiple management interfaces for easy integration and automation. The SR8 PROX supports datacasting services and its modular design allows for the aggregation of multiple demodulators, achieving bit rates over 2 Gbps.
