SCU-1800 Sweep Control Unit

The Viavi (formerly JDSU) SCU-1800 Sweep Control Unit is an advanced sweep transceiver offering updated, space-saving hardware and simple browser-based configurability. The headend/hub rack-mounted SCU-1800 provides non-interfering downstream sweep to 1,218 MHz and upstream sweep to 204 MHz on up to 16 switchable return sweep ports.

Advanced System Sweep
The ONX/SCU system meets the needs of current and evolving cable networks, with the sweep frequency range extended to 1,218 MHz forward and 204 MHz reverse. The platform is compatible with existing VIAVI sweep equipment (SDA-55xx, DSAM), offering smooth, seamless integration and a clear transition path to the next generation of network technology.

A space-conserving 1RU form factor with 16 switchable return sweep ports means less signal combining is required, resulting in improved noise performance. Sweep receivers can be consolidated to conserve cost. The SCU-1800 is remotely or locally configurable, with the configuration interface accessible via Ethernet, Internet, Intranet, or browser. Improved pulse generation performance delivers a pure, clean RF sweep signal with narrower pulses, enabling insertion between carriers.
