SCU-1800 Sweep Control Unit

The SCU-1800 Sweep Control Unit is an advanced sweep transceiver offering updated, space saving hardware and simple browser configurability.

The headend/hub rack-mounted SCU-1800 provides non-interfering downstream sweep to 1.218 GHz and upstream sweep to 204 MHz on up to 16 ports.

Advanced System Sweep

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

A space-conserving 1RU Sweep Control Unit (SCU-1800) with 16 switchable return sweep ports means less combining is required, leading to improved noise performance, and sweep receivers can be consolidated to conserve cost. The sweep control unit is remotely or locally configurable and the interface is accessible via Ethernet/Internet/Intranet and browser. Improved pulse generation performance provides a pure, clean RF sweep signal with narrower pulses enabling insertion between carriers.
