DVB-S2 Modulator (QPSK HD, IF 50~960MHz)
1 Product Overview
The IF DVB-S2 QPSK Modulator (IF 50~960 MHz) is a high-performance modulator developed in accordance with the second-generation digital video broadcasting satellite standard DVB-S2 (EN302 307). The device converts input signals via ASI or IP into digital signals and outputs them in RF (DVB-S2) format. It supports BISS scrambling, local or remote device management, LCD display and button operation. Featuring high cost-performance, high integration and strong performance, this equipment is widely used in broadcasting, interactive services, news gathering and other satellite modulation applications.
